GPX4 protein degradation agent, preparation method and application thereof, and antitumor cell drug

The invention provides a GPX4 protein degradation agent, a preparation method thereof, and an anti-tumor cell drug, and belongs to the technical field of drug application. The GPX4 protein degradation agent provided by the invention has a protein degradation targeting chimera (PROTAC) molecular structure, a mother nucleus structure of the GPX4 protein degradation agent is used as a small molecule ligand for combining target protein, an A2 substituent is used as a small molecule ligand for combining an E3 ubiquitin ligase compound, and an A1 substituent is used as a connecting group for connecting the two ligands. The GPX4 protein degradation agent with the structure can specifically recognize GPX4 protein and effectively ubiquitinate and degrade the GPX4 protein, so that tumor cell ferroptosis is induced.

Identification of novel amino acid derived CCK-2R antagonists as potential antiulcer agent: Homology modeling, design, synthesis, and pharmacology

The present study revisited the three-dimensional (3D) homology model of CCK-2R using human A2a adenosine receptor and the resolved NMR based structure of the third extracellular loop of the CCK-2R as templates. Further in order to identify novel antiulcer agents, rational designing have been performed utilizing the substructure of a well-known CCK-2R antagonist benzotript as a lead molecule and submitted to the combined docking and simulation studies. This led to the understanding of the essential structure requirement as well as variation of binding mode among conformational isomers of small molecule CCK-2R antagonists. In the next step, preparation of each configurational isomer of these molecules was carried out and submitted for their in vitro activity followed by in vivo screening into antiulcer rat model. The biological screening of these compounds has not only validated the developed homology model of CCK-2R but also led to the identification of highly potent CCK-2R antagonist 6a as an orally active and safe candidate molecule having better antiulcer properties than the well-known drug benzotript.

Synthesis and cytotoxicity evaluation of (tetrahydro-β-carboline)-1,3,5-triazine hybrids as anticancer agents

A series of tetrahydro-β-carbolines and 1,3,5-triazine hybrids have been synthesized and evaluated for their cytotoxicity against a panel of eight human cancer cell lines and normal human fibroblasts (NIH3T3). It led us to discovery of racemic compounds 69, 71 and 75, which are selectively cytotoxic towards KB (oral cancer) cell line with IC50 values of 105.8, 664.7 and 122.2?nM, respectively; while their enantiopure forms are less active and not selective. Enantiopure compound 42 showed 2.5 times more selectivity towards MCF7 cells over normal fibroblast NIH3T3 cells with an IC50 value of 740?nM, also arrests cell cycle in G1 phase and induces apoptosis in MCF7 and MDA MB231cell lines.

Synthesis of 2-[3-(7-Chloro-quinolin-4-ylamino)-alkyl]-1-(substituted phenyl)-2,3,4,9-tetrahydro-1H-β-carbolines as a new class of antimalarial agents

A series of hybrid molecules 2-[3-(7-Chloro-quinolin-4-ylamino)-alkyl]-1-(substituted phenyl)-2,3,4,9-tetrahydro-1H-β-carbolines have been synthesized and screened for their in vitro antimalarial activity against chloroquine-sensitive strains of Plasmodium falciparum. Compounds 26, 32, and 34 have shown MIC in the range of 0.05-0.11 μM and are in vitro several folds more active than chloroquine.
