Synthesis of progesterone derivatives and evaluation of their efficiency as pneumococcal vaccines
摘要:
Progesterone (1) was used as a template to develop new anticancer compounds. Ring D modification of 1, through its reaction with active methylene derivatives, gave the condensate derivatives 3a, b. The latter compounds underwent heterocyclization reactions through the reaction with either hydrazine hydrate or phenyl hydrazine to give the pyrazole derivatives 6a-d, respectively. The reaction of 1 with bromine gave the alpha-bromo derivative 7, which in turn reacted with potassium cyanide to yield the cyanoacetyl derivative 8. Compound 8 has been subjected to a series of reactions that produced benzylidene, aryl hydrazine, pyrazole, and pyran derivatives. The newly synthesized products were tested for their efficiency as pneumococcal vaccines and the results were promising.
