The synthesis of ω-(2-aryl-1,3-dioxolan-2-yl)alkyl purine derivatives and their activity towards HIV reverse transcriptase
Novel derivatives of 6-substituted purines were synthesized by alkylation of 6-substituted purines with various 2-(chloroalkyl)-2-aryl-1,3-dioxolanes and related compounds. Their inhibitory properties toward HIV reverse transcriptase were studied. The structure-activity relationship within the synthesized compounds was found.
A compound of formula wherein Y represents a pyridyl group, or a phenyl group of formula wherein R3 represents a hydrogen atom, a CF3 group or an alkoxy group, R4 represents a hydrogen atom, an alkyl group, or a CF3

NPY antagonists: spiroisoquinolinone derivatives
A series of non-peptidergic antagonists of NPY have been synthesized and are comprised of spiroisoquinolinone derivatives of Formula I. As antagonists of NPY-induced feeding behavior, these compounds and known analogs are expected to act as effective anorexiant agents in promoting weight loss and treating eating disorders.
