isclosed are novel derivatives of polyene macrolide antibiotics of the general formula
wherein M is a polyene macrolide antibiotic moiety containing an amino sugar moiety, the amino group of which is substituted by X, wherein X is
-Rs or hydrogen,
wherein A and B independently of each other are hydrogen or NR3R4 or one of A and B is hydrogen and the other is 0 -NH-C-R-NR3R4; R5 is an a-amino-acyl group; n is 1 to 3, t is zero or 1, and when t is zero p is zero to 4 and when t is I p is zero;
z is zero or 1, and
Y is hydrogen, alkyl, allyl, propargyl, benzyl or phenylpropargyl, with the proviso that, when X is hydrogen, z must be I and Y allyl, propargyl, benzyl or phenylpropargyl;
and the pharmaceutically acceptable acid addition salts thereof.
The novel compounds may be prepared by methods known per se. Preferably the compounds are prepared by reaction of respective polyene macrolide antibiotic with a reactive derivative of a compound HOX wherein the amino group(s) is (are) protected. The compounds wherein X is hydrogen and Y is allyl, propargyl, benzyl or phenylpropargyl can n be prepared by reaction of the respective N-protected polyene macrolide antibiotic with a reactive derivative of propene, propyne, phenylpropyne or toluene.
The compounds show antifungal activity and are useful in the treatment of fungal infections.
本发明公开了通式为 M 的聚烯大环内酯类抗生素的新型衍生物。
其中 M 是含有氨基糖分子的聚烯大环内酯抗生素分子,其氨基被 X 取代,其中 X 是
-Rs或氢、
其中 A 和 B 独立地为氢或 NR3R4,或 A 和 B 中的一个为氢,另一个为 0 -NH-C-R-NR3R4;R5 为 a-氨基酰基;n 为 1 至 3,t 为零或 1,当 t 为零时 p 为零至 4,当 t 为 I 时 p 为零;
z 为零或 1,以及
Y 是氢、烷基、烯丙基、丙炔基、苄基或苯丙炔基,但条件是当 X 是氢时,z 必须是 I,Y 是烯丙基、丙炔基、苄基或苯丙炔基;
及其药学上可接受的酸加成盐。
新型化合物可以通过本身已知的方法制备。这些化合物最好是通过各自的聚烯类大环内酯抗生素与化合物 HOX 的活性衍生物反应制备,其中的氨基是受保护的。X 为氢,Y 为烯丙基、丙炔基、苄基或苯丙炔基的化合物可通过各自的 N 保护聚烯大环内酯抗生素与丙烯、丙炔、苯丙炔或甲苯的活性衍生物反应制备。
这些化合物具有抗真菌活性,可用于治疗真菌感染。
