Target	HIV-1:0.005 μM (IC50)
In Vitro	UC-781 (0.05、0.2 和 0.5 % UC-781 补充凝胶；10 天) 从凝胶制剂中释放出来，并清除 CEM 感染细胞中的人类免疫缺陷病毒 (HIV)-1[1]。 UC-781 (3.75 -30 μM) 抑制蜡样芽孢杆菌的生长 (大约 50 %)[1]。 UC-781 抑制 CEM T 细胞中的 HIV-1 (ⅢB) (EC50=6 nM; IC50=23 nM)。UC-781 抑制单核细胞来源的树突状细胞 (MO-DC) 和自体 CD4+ T 细胞，EC50 值分别为 550 nM 和 1588 nM[2]。 UC-781 (1000 nM；24 h) 有效地防止或阻止了单核细胞来源的树突状细胞和自体 CD4+ T 细胞感染 HIV[2]。 UC-781 (0.001-1000 µM；2 h) 抑制病毒 (virus) 转移和宫颈外植体感染 HIV-1BaL[4]。
In Vivo	UC-781 (100 µl 5% UC-781 补充凝胶；阴道内；一天一次持续 10 天) 从凝胶制剂中释放出来，对正常组织显示低毒性[1]。 Animal Model: Female rabbit (~1200 g; 10 weeks old)[1]. Dosage: 100 µl 5% UC-781 replens gel. Administration: Intravaginal; once daily for 10 days. Result: Released from gel preparation and had normal histology without significant increases inflammatory cells in rabbits.
