alkyl, and is optionally substituted; the circle represents a mono-heterocycle or a bis-heterocycle, wherein the heterocycle, or each of the two heterocycles, is a five membered ring having at least a first ring heteroatom that is N, and optionally a second ring heteroatom that is selected from N, O, and S; and the heterocycle, or each of the two heterocycles, is optionally substituted with one or more substituents; and pharmaceutically acceptable salts, amides, esters, solvates, and hydrates thereof. The present invention also pertains to uses of such compounds, for example, to inhibit DNA Gyrase activity in a cell and in methods of therapy, for example, to treat a disease or condition that is ameliorated by the inhibition of DNA Gyrase, such as a bacterial infection, cancer, etc.; as a herbicide; as a microbicide; as a bactericide; etc.
本发明涉及微小肽B17组分单元的合成类似物,制备和使用这些类似物的方法,包括作为DNA酶抑制剂。更具体地说,本发明涉及以下式的化合物:其中:W独立地为:—H或肽基团;Z独立地为:—OH或肽基团;其中每个肽基团,如果存在,则为:氨基酸基团,包括恰好一个氨基酸,或:多肽(氨基酸)基团,包括两个或更多氨基酸;RN3独立地为:—H、C1-6烷基、C2-6烯基、C3-6环烷基或C3-6环烯基、C6-14芳基、C5-14杂芳基、C6-14芳基-C1-6烷基、C5-14杂芳基-C1-6烷基,并且可选地被取代;圆圈表示单杂环或双杂环,其中杂环或两个杂环中的每一个都是具有至少一个第一环杂原子的五元环,该原子是N,可选地,第二环杂原子是从N、O和S中选择的;并且该杂环或两个杂环可选地被一个或多个取代基取代;以及其药学上可接受的盐、酰胺、酯、溶剂化物和水合物。本发明还涉及这些化合物的用途,例如,在细胞中抑制DNA酶活性和治疗方法中使用,例如治疗通过抑制DNA酶改善的疾病或病况,如细菌感染、癌症等;作为除草剂;作为杀菌剂;作为杀菌剂等。
