Several 2,2-dimethyl-3-phenyl-1,2-dihydroquinazoline-4(3H)-thiones and 2-methyl-3-phenylquinazoline-4(3H)-thiones were synthesized and tested for their antimycobacterial, photosynthesis-inhibiting, and antialgal activity. Antimycobacterially active compounds were found among the 6-chloro substituted compounds. 6-Chloro-3-(4-isopropylphenyl)-2-methylquinazoline-4(3H)-thione exhibited higher activity than the isoniazid standard against Mycobacterium avium and M. kansasii. Most of the compounds possessed photosynthesis-inhibiting activity. 6-Chloro-2,2-dimethyl-3-phenyl-1,2-dihydroquinazoline-4(3H)-thione and its 3´-chloro- and 3´,4´-dichloro analogs were most effective in the inhibition of oxygen evolution rate in spinach chloroplasts. Of compounds selected for toxicological screening, 6-chloro-3-(4-isopropylphenyl)-2-methyl-quinazoline-4(3H)-thione was the only one active in the brine shrimp bioassay.
合成了几种2,2-二甲基-3-苯基-1,2-二氢喹啉-4(3H)-硫酮和2-甲基-3-苯基喹啉-4(3H)-硫酮,并测试了它们的抗分枝杆菌、抑制光合作用和抗藻活性。在6-氯取代的化合物中发现了具有抗分枝杆菌活性的化合物。6-氯-3-(4-异丙基苯基)-2-甲基喹啉-4(3H)-硫酮对分枝杆菌avium和M. kansasii的活性高于异烟肼标准。大多数化合物具有抑制光合作用的活性。6-氯-2,2-二甲基-3-苯基-1,2-二氢喹啉-4(3H)-硫酮及其3'-氯和3',4'-二氯类似物在抑制菠菜叶绿体氧气释放速率方面最为有效。在选择的毒理筛选化合物中,6-氯-3-(4-异丙基苯基)-2-甲基喹啉-4(3H)-硫酮是唯一在咸水虾生物测定中活性的化合物。
