The Amaryllidaceae alkaloid trans-dihydrolycoricidine 7 and three analogues 8-10 were produced via asymmetric chemical synthesis. Alkaloid 7 proved superior to acyclovir, the current standard for herpes simplex virus, type 1 (HSV-1) infection. Compound 7 potently inhibited lytic HSV-1 infection, significantly reduced HSV-1 reactivation, and more potently inhibited varicella zoster virus (VZV) lytic infection. A configurationally defined (3R)-secondary alcohol at C3 proved crucial for efficacious inhibition of lytic HSV-1 infection.
石蒜科生物碱反式二氢石蒜碱7及其三种类似物8 - 10通过不对称化学合成制备。生物碱7被证明优于阿昔洛韦,阿昔洛韦是目前治疗1型单纯疱疹病毒(HSV - 1)感染的标准药物。化合物7能有效抑制HSV - 1的裂解感染,显著降低HSV - 1的再激活,并更有效地抑制水痘带状疱疹病毒(VZV)的裂解感染。结果证明,C3位具有构型明确的(3R)-仲醇对于有效抑制HSV - 1裂解感染至关重要。
