soluble oncodazole analogue that could be easily formulated, a series of substituted oncodazoles was synthesized and evaluated for tubulinbinding affinity, in vitro cytotoxicity against cultured mouse B-16 cells, and ability to prolong lifespan at the maximally tolerated dose in the P388 mouse leukemia model. Biological evaluation of all the isomeric methyloncodazoles demonstrated the thiophene 4'-position

best activity. In particular, ortho substitution of the benzyl group with an acidic function was crucial for maximum potency. In cases similar to 32, where the benzyl group possesses an ortho carboxylate, the N-2-substituted tetrazole isomer showed 100-fold greater activity relative to the corresponding N-1 isomer. This pattern was reversed when the acid was substituted at the para position. The quinoline

The strong base induced cycloaddition of homophthalic anhydrides and relatedcompounds to halo- 1,4-naphthoquinone derivatives has been shown to provide short convergent syntheses of anthracyclinones, 4-demethoxydaunomycinone (1), daunomycinone (2), 11-deoxydaunomycinone (3), and 11-deoxycarminomycinone (4).
Carbacyclin analogs that exhibit platelet aggregation inhibition activity and other biological activites common to structurally related prostacyclins are provided.
