Acids, esters, imine acids, imine esters, and imine amides derived from 6-formyl-4,7,9-trihydroxy-1-phenazinecarboxylic acid, methyl ester and from 6-formyl-4,7,9-trihydroxy-8-methyl-1-phenazinecarboxylic acid, methyl ester demonstrate antimicrobial and antineoplastic activity.A purified strain of Streptomyces galanosa, NRRL 15738, is capable of producing 6-formyl-4,7,9-trihydroxy-8-methyl-1-phenazinecarboxylic acid, methyl ester in isolable quantities from a fermentation broth containing assimilable sources of carbon and nitrogen.
摘要:
5-Methyl-6-[[(3,4,5-trimethoxyphenyl)amino]-methyl]-2,4-quinazolinediamine (trimetrexate) has been shown to possess clinical activity against non-small cell lung cancer, head and neck squamous cancers, and breast cancer. The compound also demonstrates therapeutic synergy with several known antineoplastic agents. Methods of treating non-small cell lung cancer, head and neck cancers, and breast cancer by administering trimetrexate alone or in combination with other neoplastic agents is disclosed.
