Electric Literature of C7H5ClN2SOn September 30, 2020 ,《In Silico Design, Synthesis and Evaluation of Novel Series of Benzothiazole- Based Pyrazolidinediones as Potent Hypoglycemic Agents》 was published in Medicinal Chemistry (Sharjah, United Arab Emirates). The article was written by Haroun, Michelyne. The article contains the following contents:

The discovery of novel ligand binding domain (LBD) of peroxisome proliferator- activated receptor γ (PPARγ) has recently attracted attention to few research groups in order to develop more potent and safer antidiabetic agents. This study is focused on docking-based design and synthesis of novel compounds combining benzothiazole and pyrazolidinedione scaffold as potential antidiabetic agents. Several benzothiazole-pyrazolidinedione hybrids were synthesized and tested for their in vivo anti-hyperglycemic activity. Interactions profile of title compounds against PPARγ was examined through mol. modeling approach. All tested compounds exhibited anti-hyperglycemic activity similar or superior to the reference drug Rosiglitazone. Introducing chlorine atom and alkyl group at position-6 and -5 resp. on benzothiazole core resulted in enhancing the anti-hyperglycemic effect. Docking study revealed that such groups demonstrated favorable hydrophobic interactions with novel LBD Ω – pocket of PPARγ protein. Among the tested compounds, N-(6-chloro-5-methylbenzo[d]thiazol-2-yl-4-(4((3,5- dioxopyrazolidin-4-ylidene)methyl)phenoxy)butanamide) 5b was found to be the most potent compound and provided valuable insights to further develop novel hybrids as anti-hyperglycemic agents.6-Chlorobenzothiazol-2-ylamine(cas: 95-24-9Electric Literature of C7H5ClN2S) was used in this study.

To discover new agrochems. with prominent pesticidal properties, a series of novel β-naphthol derivatives containing benzothiazolylamino and various heteroaryl groups I (R = H, CF3, Cl; Het = pyrazol-5-yl, imidazol-2-yl, pyrimidin-5-yl, etc.) were efficiently synthesized via Betti reaction. The bioassay results showed that most of the synthesized compounds exhibited favorable insecticidal potentials, particularly towards oriental armyworm (50-100% at 200 mg·L-1) and diamondback moth (50-95% at 10 mg·L-1). Some compounds possessed LC50 values of 0.0988-5.8864 mg·L-1 against diamondback moth. Compounds I (R = H; Het = 2-phenyl-2H-1,2,3-triazol-4-yl), I (R = H; Het = 6-chloroimidazo[1,2-a]pyridin-3-yl), I (R = H; Het = 6-bromoimidazo[1,2-a]pyridin-3-yl) also displayed lethality rates of 30-90% against spider mite at the concentration of 100 mg·L-1. Overall, some compounds could be considered as new insecticidal/acaricidal leading structures for further investigation. The calcium imaging experiments revealed that compound I (R = H; Het = 3-bromo-1-(3-chloropyridin-2-yl)-1H-pyrazol-5-yl), I (R = H; Het = 2-phenyl-2H-1,2,3-triazol-4-yl), and 1-((benzo[d]thiazol-2-ylamino)(4-methoxyphenyl)- Methyl)naphthalen-2-ol could activate the release of calcium ions in insect (M. separata) central neurons at a higher concentration (50 mg·L-1).
