Design and synthesis of 2-(2,6-dibromophenyl)-3-heteroaryl-1,3-thiazolidin-4-ones as anti-HIV agents
摘要:
A series of 2-(2,6-dibromophenyl)-3-heteroaryl-1,3-thiazolidin-4-ones were designed, synthesized and evaluated as selective human immunodeficiency virus type-1 reverse transcriptase (HIV-1 RT) enzyme inhibitors. The results of the HIV-1 RT kit and in vitro cell based assay showed that eight compounds effectively inhibited HIV-1 replication at 20-320 nM concentrations with minimal cytotoxicity in MT-4 as well as in CEM cells.

ring, displayed the best antagonistic activity against FXR with good cellular potency (IC50=12.2±0.2 μM). Eventually, this compound was used as a probe in a molecular dynamics simulation assay. Our results allowed us to propose an essential molecular basis for FXR antagonism, which is consistent with a previously reported antagonistic mechanism; furthermore, E467 on H12 was found to be a hot‐spot residue

Palladium-Catalyzed (3+3) Annulation of Allenylethylene Carbonates with Nitrile Oxides
In this paper, we designed and synthesized a new type of cyclic carbonates, allenylethylene carbonates (AECs). With AECs as reactive precursors, we developed palladium-catalyzed (3+3) annulation of AECs with nitrile oxides. Various AECs worked well in this reaction under mild reaction conditions. A variety of 5,6-dihydro-1,4,2-dioxazine derivatives with allenyl quaternary stereocenters can be accessed
