3-氨基-4-甲基苯甲酸用作起始原料合成具有潜在抗肿瘤活性的环丙胂化合物。此外,它还具有部分除草活性。
制备将0.5克3-硝基-4-甲基苯甲酸(2.76毫摩尔,1.0当量)溶解在30毫升甲醇中,加入5%钯/炭催化剂并在氢气氛下剧烈搅拌3小时。随后,通过短硅胶柱用乙酸乙酯过滤除去催化剂,真空浓缩有机相。最终获得400毫克呈淡黄色固体的3-氨基-4-甲基苯甲酸(2.65毫摩尔,96%产率)。

The efficacy and side-effects of drugs do not just reflect the biochemical and pharmacodynamic properties of the parent compound, but often comprise of cooperative effects between the properties of the parent and active metabolites. Metabolites of imatinib, nilotinib and midostaurin have been synthesised and evaluated in assays to compare their properties as protein kinase inhibitors with the parent drugs. The N-desmethyl-metabolite of imatinib is substantially less active than imatinib as a BCR-ABL1 kinase inhibitor, thus providing an explanation as to why patients producing high levels of this metabolite show a relatively low response rate in chronic myeloid leukaemia (CML) treatment. The hydroxymethylphenyl and N-oxide metabolites of imatinib and nilotinib are only weakly active as BCR-ABL1 inhibitors and are unlikely to play a role in the efficacy of either drug in CML. The 3-(R)-HO-metabolite of midostaurin shows appreciable accumulation following chronic drug administration and, in addition to mutant forms of FLT3, potently inhibits the PDPK1 and VEGFR2 kinases (IC50 values
