the Bcl-2 family. Herein we describe the synthesis of obatoclax derivatives by replacement of the pyrrole and indole ring of obatoclax with thiophene, furan and thiazolidinedione. The in vitro cytotoxicity of the newly synthesized compounds is evaluated against hepatocellular carcinoma cells. Pyrrole and indole substituents of obatoclax analogues exhibited potent inhibition of cell growth. Among the tested

Marine alkaloids were divided into five categories from the perspective of anti-tumor activity. The optimization process, chemical synthesis, anti-tumor activity evaluation and structure–activity relationship of various compounds were discussed.

heteroaromatic substituents. The synthesized GAT211 analogs were then evaluated in vitro as CB1R allosteric modulators in cAMP and β-arrestin2 assays with CP55,940 as the orthosteric ligand. Furan and thiophene rings (15c-f and 15m) were the best-tolerated substituents at the C2 position of GAT211 for engagement with human CB1R (hCB1R). The SAR around the novel ligands reported allowed direct experimental characterization
The synthesis of new isogranulatimide analogues, their inhibitory activities toward the Checkpoint 1 kinase (Chk1), and their in vitro cytotoxicities toward four tumor cell lines (one murine L1210 leukemia, and three humancell lines: DU145 prostate carcinoma, A549 non-smallcelllungcarcinoma, and HT29 colon carcinoma) are described. The affinity for DNA of some representative compounds and their
