Quinolone antibacterial agents substituted at the 7-position with spiroamines. Synthesis and structure-activity relationships
摘要:
A series of fluoroquinolone antibacterials having the 7-position (10-position of pyridobenzoxazines) substituted with 2,7-diazaspiro[4.4]nonane (4b), 1,7-diazaspiro[4.4]nonane (5a), or 2,8-diazaspiro[5.5]undecane (6b) was prepared, and their biological activities were compared with piperazine and pyrrolidine substituted analogues. Most exhibited potent Gram-positive and Gram-negative activity, especially when side chain 4b was N-alkylated.
Dispiromacrocycles: A class of diamide and diimide ionophores
摘要:
A series of novel ionophores was synthesized in three steps from acrylonitrile and diethyl malonate or malononitrile via 2,8-diazaspiro[5,5]undecane-1,7-dione (7) or 2,8-diazaspiro[5,5]undecane-1,3,7,9-tetrone (8). Spirodiamide macrocycle 14 imparts selectivity for lithium to potentiometric ion-selective electrodes.
