There has been prepared a series of secondary and tertiary amide derivatives of the polyene antibiotic partricin as well as of its single components, partricin A and B, having radicals on the amide nitrogen, said radicals being preferably substituted, in turn, with various amine groups. The synthesis has been carried out by reacting the C-18 carboxyl of the polyene with suitable amines, in the presence of diphenyl phosphorazidate as activator.
From said amines, especially those substituted with basic groups, many salts with a good water solubility have been prepared by reacting them with pharmacologically compatible acids.
It has been shown that many amines and related salts are more active than, or as active as, the starting product as antimycotic and antiprotozoan agents, while being less toxic and less hemolytic, and can therefore find a useful application in the clinical and veterinary therapy. The compounds can also be used in the treatment of hypercholesteremia and hyperlipemia conditions and of some steroid hormones unbalances, as well as in the pharmacological therapy of hypertrophic prostate, and in the treatment of lipid envelope virus infections.
现已制备出一系列聚烯类抗生素部分霉素及其单一成分部分霉素 A 和 B 的仲酰胺和叔酰胺衍生物,这些衍生物的酰胺氮上具有基团,所述基团最好依次被各种胺基团取代。合成的方法是:在作为活化剂的磷酸二苯酯存在下,将聚烯的 C-18 羧基与合适的胺反应。
上述胺类,特别是那些被碱性基团取代的胺类,通过与药理学上相容的酸反应,制备出了许多水溶性良好的盐类。
研究表明,许多胺和相关盐类作为抗霉菌剂和抗原虫剂的活性高于或等同于起始产物,同时毒性和溶血性较低,因此可以在临床和兽医治疗中得到有用的应用。这些化合物还可用于治疗高胆固醇血症、高血脂症和某些类固醇激素失衡,以及肥大性前列腺的药物治疗和脂质包膜病毒感染的治疗。
