iPSC Neuronal Assay Identifies Amaryllidaceae Pharmacophore with Multiple Effects against Herpesvirus Infections
摘要:
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.

2-Dialkenylcyclopropanes incorporating a vinyl azide, generated by Knoevenagel condensations between the corresponding cyclopropanecarbaldehydes and α-azido ketones, undergo cascade Cope and Winstein [3,3]-sigmatropic rearrangements, under mild conditions. The sequence allows access to diversely substituted 1,4-cycloheptadienes armed with a secondary allylic azide with up to three stereocenters.
