- the biosynthetic production of wortmannin is well known in the art and the analogs are synthesized from wortmannin.
- wortmannin is produced by the fermentation of any one of a number of previously disclosed microorganisms such as Talaromyces wortmannin and Penicillium wortmannin, Myrothecium roridium, and Fusarium. Following fermentation, wortmannin is extracted and purified via known methods. Preferably, wortmannin is microbially synthesized and isolated in substantially pure form from a fermentation culture) one such fermentation culture is identified as A24603.1).
- Wortmamiin can be recovered using various isolation and purification procedures understood in the art.
- the medium used to grow the culture can be any one of a number of media.
- preferred carbon sources in large-scale fermentation are glucose and soluble starch such as corn starch.
- Maltose, ribose, xylose, fructose, galactose, mannose, mannitol, potato dextrin, methyl oleate, oils such as soybean oil and the like can also be used.
- Preferred nitrogen sources are enzyme-hydrolyzed casein and cottonseed flour, although pepsinized milk, digested soybean meal, fish meal, corn steep liquor, yeast extract, acid- hydrolyzed casein, beef extract, and the like can also be used.
- the nutrient inorganic salts that can be incorporated in the culture media are the customary soluble salts capable of yielding calcium, magnesium, sodium, ammonium, chloride, carbonate, sulfate, nitrate, zinc, and like ions.
- Essential trace elements necessary for the growth and development of the organism also should be included in the culture medium. Such trace elements commonly occur as impurities in other substituents of the medium in amounts sufficient to meet the growth requirements on the organism.
- wortmamiin For production of substantial quantities of wortmannin, submerged aerobic fermentation in stirred bioreactors is preferred. Small quantities of wortmamiin may be obtained by shake- flask culture. Because of the time-lag in production commonly associated with inoculation of large bioreactors with the spore form of the organism, it is preferable to use vegetative inoculum.
- the vegetative inoculum is prepared by inoculating a small volume of culture medium with the spore form or mycelial fragments of the organism to obtain a fresh, actively growing culture of the organism.
- the vegetative inoculum medium can be the same as that used for larger fermentations, but other media are also suitable.
- wortmannin can be recovered from the fermentation medium by methods used in the art.
- the wortmannin produced during fermentation of the A24603.1 organism for example, occurs mainly in the broth.
- wortmannin can be recovered from the biomass by a variety of techniques.
- a preferred technique involves filtering whole fermentation broth with a ceramic filter. The filtrate is eluted with an organic solvent such as ethyl acetate and concentrated. The concentrate is suspended in alcohol until crystallization occurs and the solution is filtered, washed and dried. For confirmation, the crystalline material is dissolved in an organic solvent and chiOmatographed on a reverse-phase silica gel absorbent (C 8 or C 18 ). Fractions are eluted in an organic-aqueous buffer such as 60% acetonitrile.
- Wortmannin may be further manipulated to arrive at the compounds of the present invention. Although the synthesis of particular analogs of wortmannin are illustrated below, other synthetic schemes common in the art will allow one ordinarily skilled in the art to synthesize compounds in accordance with the present invention, and the synthetic schemes set forth herein should, in no way, be considered limiting.
- a wortmannin analog of Figures 1- 3 may be administered as such, or can be compounded and formulated into pharmaceutical compositions in unit dosage form for parenteral, transdermal, rectal, nasal, local intravenous administration, or, preferably, oral administration.
- Such pharmaceutical compositions are prepared in a manner well known in the art and comprise at least one active compound selected from the group consisting of those wortmannin analogs of Figs 1-3 associated-with a pharmaceutically earner.
- active compound refers to at least one compound selected from compounds of the formulas or pharmaceutically acceptable salts thereof.
- an effective amount means an amount of a compound of the present invention that is capable of inhibiting, blocking, or reversing the activation, migration, or proliferation of cells.
- the activity contemplated by the present methods includes both medical therapeutic and/or prophylactic treatment, as appropriate.
- the specific dose of a compound administered according to this invention to obtain therapeutic and/or prophylactic effects will, of course, be determined by the particular circumstances surrounding the case, including, for example, the compound administered, the route of administration, and the condition being treated.
- the compounds are effective over a wide dosage range and, for example, dosages per day will normally fall within the range of from 0.001 to 10 mg/kg, more usually in the range of from 0.01 to 1 mg/kg.
- the effective amount administered will be determined by the physician in the light of the relevant circumstances including the condition to be treated, the choice of compound to be administered, and the chosen route of administration, and therefore the above dosage ranges are not intended to limit the scope of the invention in any way.
- the term “inhibiting” includes the administration of a compound of the present invention to prevent the onset of the symptoms, alleviating the symptoms, or eliminating the disease, condition or disorder.
- the active compound is known as "active ingredient".
- the active ingredient will usually be mixed with a carrier, or diluted by a carrier, or enclosed within a carrier that may be in the form of a capsule, sachet, paper or other container.
- the carrier serves as a diluent, it may be a solid, semisolid, or liquid material that acts as a vehicle, excipient of medium for the active ingredient.
- composition can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, emulsions, solutions, syrups, suspensions, soft and hard gelatin capsules, sterile injectable solutions, and sterile packaged powders.
- Suitable carriers, excipients, and diluents include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate alginates, calcium salicate, macrocrystalline cellulose, polyvinylpyrrolidone, cellulose, tragacanth, gelatin, syrup, methyl cellulose, methyl- and propylhydroxybenzoates, talc, magnesium stearate, water, and mineral oil.
- the fonnulations can additionally include lubricating agents, wetting agents, emulsifying and suspending agents, preserving agents, sweetening agents or flavoring agents.
- the compositions may be formulated so as to provide quick, sustained, or delayed release of the active ingredient after administration to the patient by employing procedures well known in the art.
- a compound for oral administration, can be admixed with carriers and diluents, molded into tablets, or enclosed in gelatin capsules.
- the mixtures can alternatively be dissolved in liquids such as 10% aqueous glucose solution, isotonic saline, sterile water, or the like, and administered intravenously or by injection.
- pharmaceutically acceptable it is meant the carrier, diluent or excipient must be compatible with the other ingredients of the formulation and not deleterious to the recipient thereof.
- the local delivery of inhibitory amounts of active compound for the treatment of cancer can be by a variety of techniques that administer the compound at or near the proliferative site.
- Examples of local delivery techniques are not intended to be limiting but to be illustrative of the techniques available. Examples include local delivery catheters, site specific carriers, implants, direct injection, or direct applications. Local delivery by a catheter allows the administration of a pharmaceutical agent directly to the proliferative site.
- Local delivery by an implant describes the surgical placement of a matrix that contains the pharmaceutical agent into the proliferative lesion.
- the implanted matrix releases the pharmaceutical agent by diffusion, chemical reaction, or solvent activators.
- Another example is the delivery of a phannaceutical agent by polymeric endoluminal sealing.
- This technique uses a catheter to apply a polymeric implant to the interior surface of the lumen.
- the pharmaceutical agent incorporated into the biodegradable polymer implant is thereby released at the surgical site. It is described in PCT WO 90/01969 (Schindler, Aug. 23, 1989).
- microparticulates may be composed of substances such as proteins, lipids, carbohydrates or synthetic polymers. These microparticulates have the pharmaceutical agent incorporated throughout the microparticle or over the microparticle as a coating. Delivery systems incorporating microparticulates are described in Lange, Science 249: 1527-1533 (September, 1990) and Mathiowitz, et al, J. App. Poly. Sci., 26:809 (1981).
- Local delivery by site specific carriers describes attaching the pharmaceutical agent to a carrier which will direct the drug to the proliferative lesion.
- Examples of this delivery technique include the use of carriers such as a protein ligand or a monoclonal antibody.
- Local delivery by direct application includes the use of topical applications.
- An example of a local delivery by direct application is applying the pharmaceutical agent to the arterial tumor or area left behind after resection of the tumor..
- Y is a heteroatom and Rl or R2 are unsaturated alkyl, non-linear alky, branched alky, substituted alkyl or cyclic alkyl.
- Rl or R2 are unsaturated alkyl, non-linear alky, branched alky, substituted alkyl or cyclic alkyl.
- the present invention has a chemical formula corresponding to those shown in Figs 1-3. Even more preferably, the present invention has a chemical formula in accordance with those shown in Fig. 2.
- the proliferation of cells is dependent on the PI 3-kinase - AKT - mTOR signaling pathway.
- signaling through PI 3-kinase and AKT appears to inhibit apoptosis.
- ND not determined
- NE non evaluable insufficient drug a 2 day MTT assay
- mean of 60 cell lines b lymphocyte toxicity at the MTD or highest dose tested expressed relative to wortmannin c liver toxicity measured by the % ALT and AST at the MTD or highest dose tested expressed relative to wortmannin d liver toxicity measured relative to wortmannin/decrease in blood lymphocytes relative to wortmannin e MTD >10% body weight loss f estimated value
- the ability of wortmannin and the analogues to inhibit phosphatidylinositol-3-kinase and mTOR is expressed as the dose to cause 50% inhibition (IC 5 o).
- C toto /ctty-Growth inhibition of human MCF-7 breast cancer cells was measured over 4 days using the MTT assay expressed as the dose to cause 50% inhibition (IC 50 ).
- Toxicity - Groups of 3 C57BL6 mice were administered wortmannin at doses of 1,2 or 3 mg/kg or the analogues at 1, 3, 9 or 18 mg/kg where sufficient compound was available by the intraperitoneal route daily for 4 days. The animals were killed 24 hr after the last dose and differential blood counts and serum chemistry determined. The major toxicities observed were liver toxicity and lymphocytopenia with decreased red blood cell counts and increased serum glucose at higher doses.
- Toxicities are measured at the maximum tolerated dose or the highest dose tested Liver toxicity is measured as the mean percent increase in serum ALT and AST expressed relative to wortmannin as 1.0. Lymphocytopenia is expressed as the percent decrease in lymphocyte counts relative to wortmannin as 1.0. A low liver toxicity and a high lymphocyte toxicity as a surrogate for inhibition of tumor cell growth is the desirable feature. Highlighted are the compounds being made for antitumor testing. Based on the above evidence, it would appear that an inhibitor of PI 3-kinase will inhibit cell growth and survival.
- PI 3-kinase inhibitors should also inhibit the local inflammatory response, especially in the case of a bioprosthetic implant, which could be favorable factor for long-term engraftment or other bioprosthetic implant.
- the wortmannin derivatives could be ideal agents for inducing a temporary block of the PI 3-kinase - AKT- mTOR pathway.
- Fig. 4-9 illustrate the effect of Wortmannin and Analogs (See Fig. 2) against PC-3
- the present invention may be utilized to treat vascular restenosis.
- Vascular restenosis is a major long-term complication following surgical intervention of blocked arteries by percutaneous transluminal coronary angioplasty (PTCA), atherectomy, laser angioplasty and arterial bypass graft surgery. In about 35% of the patients who undergo PTCA, reocclusion occurs within three to six months after the procedure.
- the current strategies for treating vascular restenosis include mechanical intervention by devices such as stents or pharmacologic therapies including heparin, low molecular weight heparin, coumarin, aspirin, fish oil, calcium antagonist, steroids, and prostacyclin.
- vascular restenosis after percutaneous transluminal coronary angioplasty has been shown to be a tissue response characterized by an early and late phase.
- the early phase occurring hours to days after PTCA is due to thrombosis with some vasospasms while the late phase appears to be dominated by excessive proliferation and migration of smooth muscle cells.
- the increased cell motility and colonization by smooth muscle cells and macrophages contribute significantly to the pathogenesis of the disease.
- the excessive proliferation and migration of vascular smooth muscle cells may be the primary mechanism to the reocclusion of coronary arteries following PTCA, atherectomy, laser angioplasty and arterial bypass graft surgery.
- the invention is comprised of stents or other devices such as bioprosthetic implants that may be coated with the wortmannin analogs.
- the present invention is also directed to methods comprised of administering wortmannin analogs to a subject at a pharmaceutically effective dose of a compound.
- the wortmannin analogs may be any of those described herein, but are preferably selected from the group of consisting of those wortmannin analogs described in Figs 1-3, even more preferably Fig. 2.
- the wortmannin analogs of the present invention expected to be useful in treating restenosis are represented by the following general chemical formula:
- Y is a heteroatom, preferably N or S
- Rl or R2 are unsaturated alkyl, non-linear alky, branched alky, substituted alkyl or cyclic alkyl.
- the local delivery of inhibitory amounts of active compound for the treatment of restenosis can be by a variety of techniques that administer the compound at or near the proliferative site. Examples of local delivery techniques are not intended to be limiting but to be illustrative of the techniques available. Examples include local delivery catheters, site- specific carriers, implants, coated implants, direct injection, or direct applications. Local delivery by a catheter allows the administration of a pharmaceutical agent directly to the proliferative lesion.
- Local delivery by an implant describes the surgical placement of a matrix that contains the pharmaceutical agent into the proliferative lesion.
- the implanted matrix releases the pharmaceutical agent by diffusion, chemical reaction, or solvent activators.
- Stents are designed to mechanically prevent the collapse and reocclusion of the coronary arteries. Incorporating a pharmaceutical agent into the stent delivers the drug directly to the proliferative site. Local delivery by this technique is described in Kohn, Pharmaceutical Technology (October, 1990).
- Another example is a delivery system in which a polymer that contains the pharmaceutical agent is injected into the lesion in liquid form. The polymer then cures to form the implant in situ. This technique is described in PCT WO 90/03768 (Donn, Apr. 19, 1990).
- Local delivery by site-specific carriers describes attaching the pharmaceutical agent to a carrier that will direct the drug to the proliferative lesion.
- Examples of this delivery technique include the use of carriers such as a protein ligand or a monoclonal antibody.
- Local delivery by direct application includes the use of topical applications.
- An example of a local delivery by direct application is applying the pharmaceutical agent directly to the arterial bypass graft during the surgical procedure.
- Y is a heteroatom and Rl or R2 are unsaturated alkyl, non-linear alky, branched alky, substituted alkyl or cyclic alkyl.
- Rl or R2 are unsaturated alkyl, non-linear alky, branched alky, substituted alkyl or cyclic alkyl.
- the present invention has a chemical formula corresponding to those shown in Figs 1-3. Even more preferably, the present invention has a chemical formula in accordance with those shown in Fig. 2.
- Restenosis is major clinical problem after coronary intervention with coronary stent implantation.
- the smooth muscle that lines the affected coronary artery undergoes hyperplasia and proliferation, due either to transient hypoxia or to an inflammatory response (or a combination of these factors) as a result of the intervention.
- the proliferation of vascular smooth muscle cells is strongly dependent on the PI 3-kinase - AKT - mTOR signaling pathway.
- signaling through PI 3-kinase and AKT appears to inhibit apoptosis of smooth muscle cells, which would also increase the mass of the smooth muscle layer in the diseased artery.
- PI 3-kinase inhibitors should also inhibit the local inflammatory response to the implant, which could be favorable factor for long-term stent engraftment or other bioprosthetic implant.
- the wortmannin derivatives could be ideal agents for inducing a temporary block of the PI 3-kinase - AKT- mTOR pathway in the local micro environment surrounding the implanted stent.
