微生物药物筛选研究进展

微生物药物是指具有抗微生物作用及其它生理活性的微生物次生代谢产物及其衍生物。具有抗微生物感染及抗肿瘤等作用的抗生素是人类在二十世纪取得抗感染决定性胜利的最重要的武器 ,是经典的微生物药物 ,其在临床上占有不可替代的重要地位。而近二十年来不断发现和开发成功的非抗菌性的特异性酶抑制剂、免疫调节剂和受体拮抗剂等的生理活性物质已经成为当今微生物药物研究与开发的主体。微生物药物的筛选研究符合药物筛选的一般规律 ,但又有其自身的特殊性。药物筛选是指以获得新型药物先导化合物为目标的新药发现过程。经典微生物药物———…

Progresses in the screening of new microbial drugs

Microbial drugs are antibiotics and other pharmacological substances from the secondary metabolites of microorganisms Screening process includes collection of soil and ocean samples, isolation of microorganisms, fermentation, strain screening, isolation of bioactive components and structure elucidation Producing microorganisms includes streptomyces, rare actinomycetes, bacteria, fungi, and ocean microorganisms New strategy for screening new microbial drugs is the screening of novel anti resistant bacterial agents, antifungal agents, antiviral agents, antitumor substances, immunomodulators and pharmacological active substances
