Disclosed is a compound which has antibiotic activity in vivo in a mammalian, preferably a human, subject, the compound comprising an uptake moiety linked to a bactericidal or bacteriostatic toxic moiety, said uptake moiety facilitating uptake of the compound by bacteria on which the toxic moiety exerts a bactericidal or bacteriostatic effect, wherein: (a) the compound is non-toxic for mammalian subjects; (b) the linkage between the uptake moiety and the toxic moiety is one which is cleavable by an enzyme or enzymes produced by the bacteria to be killed/inhibited, but is not readily cleavable by enzymes produced by the subject and to which the compound is exposed prior to contacting the bacteria; and (c) the toxic moiety, when cleaved from the uptake moiety, is toxic for the bacteria, but not toxic for the subject.
本文揭示了一种化合物,在哺乳动物体内,特别是在人体中具有抗生素活性,该化合物包括一个与细菌杀菌或细菌抑制毒性部分相连的摄取基团,所述摄取基团促进细菌摄取该化合物,该毒性部分对细菌产生细菌杀菌或细菌抑制作用,其中:(a) 该化合物对哺乳动物体不具有毒性;(b) 摄取基团与毒性部分之间的连接是一种可被细菌产生的酶或酶裂解的连接,但不容易被主体产生的酶裂解,且在接触细菌之前暴露于主体的化合物;(c) 当毒性部分从摄取基团中裂解时,对细菌具有毒性,但对主体不具有毒性。
