Process for the production of optically active (+)-bicyclo[3.3.0]octanol derivatives of formula (+)-I, in which R.sub.1 and R.sub.2 represent jointly an oxygen atom or the double-bond residue --O--X--O-- with X as a straight or branched-chain alkylene with 1-7 C-atoms, or R.sub.1 and R.sub.2 represent separately the residue OR.sub.5 with R.sub.5 as a straight or branched-chain alkyl with 1-7 C-atoms, and R.sub.3 the residue COOZ with Z as a hydrogen atom, straight or branched chain alkyl with 1-7 C atoms, cycloalkyl with 3-6 C atoms, phenyl or aralkyl with 7-10 atoms or R.sub.3 is the residue --(CH.sub.2).sub.n --O--COR.sub.4 with n having the meaning 1-4 and R.sub.4 as a straight or branched-chain alkyl with 1-7 C atoms, cycloalkyl with 3-6 C atoms, phenyl or aralkyl with 7-10 C atoms. The process is characterized in that racemic 3.alpha.-cyloxy-cis-bicyclo[3.3.0]-octane derivatives of formula (+)-II, wherein R.sub.1, R.sub.2 R.sub.3 and R.sub.4 have the above meanings, are subjected enzymatically or microbiologically to a stereospecific acylate hydrolsis and the (+)-bicyclo[3.3.0]-octanol derivative produced is separated from the unsaponified bicyclo[3.3.0]-octanol acylate of formula (-)-II or the unsaponified enantiomers (+)-II are separated from the saponified bicyclo[3.3.0]octanol derivative (-)-I and then subjected to chemical acylate hydrolysis.

Claimed is a process for the production of optically active bicyclo[3.3.0]octanedione-carboxylic acid esters of Formula I ##STR1## wherein R.sub.1 and R.sub.2 jointly represent an oxygen atom, orR.sub.1 and R.sub.2 individually represent the residue OR.sub.4 where R.sub.4 means methyl- or ethyl-, andR.sub.3 is a straight or branched-chain alkyl group of 1-3 carbon atoms,comprising enantioselectively saponifying and decarboxylating with .alpha.-chymotrypsin an optically inactive, prochiral bicyclo[3.3.0]octanedionedicarboxylic acid diester of Formula II ##STR2## wherein R.sub.1, R.sub.2 and R.sub.3 have the meanings set forth above, and recovering a compound of Formula I.
摘要:
This invention describes the new 6-alkenyl- and 6-alkinyl-epothilone derivatives of general formula (I) in which R1a, R1b, R2a, R3a, R3b, R4, R5, R6, R7, A, Y, D, E, G, Y and Z have the meanings that are indicated in the description. The new compounds interact with tubulin by stabilizing microtubuli that are formed. They are able to influence the cell-splitting in a phase-specific manner and thus find use in treating diseases or conditions associated with the need for cell growth, division and/or proliferation. Thus the compounds are suitable for treating malignant tumors, for example, ovarian, stomach, colon, adeno-, breast, lung, head and neck carcinomas, malignant melanoma, acute lymphocytic and myelocytic leukemia. In addition, they are suitable for anti-angiogenesis therapy as well as for treatment of chronic inflammatory diseases (such as psoriasis, arthritis). Methods of use and preparation of the compounds are also described.

This invention relates to the new epothilone derivatives of general formula I, in which substituents Y, Z, R2a, R2b, R3, R4a, R4b, D-E, R5, R6, R7, R8 and X have the meanings that are indicated in more detail in the description.The new compounds interact with tubulin by stabilizing microtubuli that are formed. They are able to influence the cell-splitting in a phase-specific manner and are suitable for treating malignant tumors, for example, ovarian, stomach, colon, adeno-, breast, lung, head and neck carcinomas, malignant melanomas, acute lymphocytic and myelocytic leukemia. In addition, they are suitable for anti-angiogenesis therapy as well as for treatment of chronic inflammatory diseases (psoriasis, arthritis). To avoid uncontrolled proliferation of cells and for better compatibility of medical implants, they can be applied or introduced into polymer materials.The compounds according to the invention can be used alone or to achieve additive or synergistic actions in combination with other principles and classes of substances that can be used in tumor therapy.
