英文摘要:

Objective:To synthesize novel tetrahydroisoquinolines with both anti-fungal and contraceptive activities, so as to provide precursor structures for contraceptives with anit-fungal activities. Methods: 3,4-dimethoxyphenylethylamine was taken as the template and the title compounds were synthesized through Pictet-Spengler reaction, neutralization reaction, substitution, hydrolysis, and acylation. The anti-fungal activity and sperm-killing activity of the target compounds were tested in vitro. Results: Fourteen title compounds were obtained and they were: 2-octyl-6, 7-dimethyl-1, 2, 3, 4-tetrahydro-isoquinoline hydrochloride(1), 2-nonyl-6,7-dimethyl-1,2,3,4-tetrahydro-isoquinoline hydrochloride (2), 2-decyl-6,7-dimethy- 1,2,3,4-tetrahydroisoquinoline hydrochloride(3), 2-dodecyl-6,7-dimethyl-1,2,3,4-tetrahydro-isoquinoline hydrochloride(4), 2-dodecyl-6,7-diacetoxy-1, 2,3,4-tetrahydro-isoquinoline hydrochloride(5 ), 2-pentyl-6,7-diacetoxy-1,2,3,4-tetrahydro-isoquinoline hydrobromide(6), 2-hexyl-6, 7-diacetoxy-1,2,3,4-tetrahydro-isoquinoline hydrobromide (7), 2-heptyl-6,7-diacetoxy-1,2,3,4-tetrahydro-isoquinoline hydrobromide (8), 2-octyl-6,7-dimethyl-1,2,3,4-tetrahydro-isoquinoline hydrobromide(9), 2-nonyl-6,7-dimethyl-1,2,3,4-tetrahydro-isoquinoline hydrobromide(10), 2-decyl-6, 7-dimethy-1,2, 3, 4-tetrahydro-isoquinoline hydrobromide ( 11 ), 2-dodecyl-6, 7-dihydroxyl-1,2, 3, 4- tetrahydro-isoquinoline hydrobromide (12), 2-tetradecyl-6, 7-dihydroxyl-1,2, 3,4-tetrahydro-isoquinoline hydrobromide (13), and 2- cetyl-6,7-dihydroxyl-1,2,3,4-tetrahydro-isoquinoline hydrobromide(14). Compounds 5-14 were firstly reported. It was found that all the 14 compounds had anti-fungal activity and 6 compounds also showed sperm-killing activities, with compounds 11,12 having the strongest activities. Conclusion: A group of novel compounds with both anti-fungal and contraceptive activities have been synthesized, which provide a precursor structure for developing new contr
