Analogues of methyllycaconitine (MLA) based on a (3-ethyl-9-methylidene-3-azabicyclo[3.3.1]nonan-1-yl)methanol template have been designed and synthesised that incorporate the modified ester sidechains distinct from that present in the natural product. Electrophysiology experiments using Xenopus oocytes expressing nicotinic acetylcholine receptors (nAChRs) revealed selected analogues served as non-competitive inhibitors that showed selectivity for the α4β2α7 nAChR subtypes, and selectivity for the (α4)3(β2)2(α4)2(β2)3 stoichiometry. This study more clearly defines the biological effects of MLA analogues and identifies strategies for the development of MLA analogues as selective ligands for the α4β2 nAChR subtype.

An operationally simple protocol is disclosed to facilitate entry to benzo-3,4-coumarins directly from biaryl carboxylic acids without the need for substrate prefunctionalization. Complementary to classic lactonization strategies, this disconnection relies on the oxidation competence of photoactivated (-)-riboflavin (vitamin B2) to generate the heterocyclic core via photoinduced single electron transfer. Collectively, the inexpensive nature of the catalyst, ease of execution, and absence of external metal additives are a convincing endorsement for the incorporation of simple vitamins in contemporary catalysis.
1-HYDROXY NAPHTHYRIDINE COMPOUNDS AS ANTI-HIV AGENTS
-
, (2008/06/13)
1-Hydroxy naphthyridine compounds (e.g., 1-hydroxy naphthyridin-2(1H)-one compounds of Formula I are inhibitors of HIV integrase and/or HIV RNase H and inhibitors of HIV replication: (I) wherein X and R1-R6 are as defined herein. The compounds are useful in the prophylaxis and treatment of infection by HIV and in the prophylaxis, delay in the onset, and treatment of AIDS. The compounds are employed against HIV infection and AIDS as compounds per se or in the form of pharmaceutically acceptable salts. The compounds and their salts can be employed as ingredients in pharmaceutical compositions, optionally in combination with other anti-HIV agents such as HIV antivirals, immunomodulators, antibiotics and vaccines.
