Design and Evaluation of Bispidine-Based SARS-CoV-2 Main Protease Inhibitors was written by Shcherbakov, Dmitriy;Baev, Dmitriy;Kalinin, Mikhail;Dalinger, Alexander;Chirkova, Varvara;Belenkaya, Svetlana;Khvostov, Aleksei;Krut’ko, Dmitry;Medved’ko, Aleksei;Volosnikova, Ekaterina;Sharlaeva, Elena;Shanshin, Daniil;Tolstikova, Tatyana;Yarovaya, Olga;Maksyutov, Rinat;Salakhutdinov, Nariman;Vatsadze, Sergey.

For the first time, derivatives of 3,7-diazabicyclo[3.3.1]nonane (bispidine) were proposed as potential inhibitors of the SARS-CoV-2 main viral protease (3-chymotrypsin-like, 3CLpro). Based on the created pharmacophore model of the active site of the protease, a group of compounds were modeled and tested for activity against 3CLpro. The 3CLpro activity was measured using the fluorogenic substrate Dabcyl-VNSTLQSGLRK(FAM)MA; the efficiency of the proposed approach was confirmed by comparison with literature data for ebselen and disulfiram. The results of the experiments performed with bispidine compounds showed that 14 compounds exhibited activity in the concentration range 1-10\u03bcM, and 3 samples exhibited submicromolar activity. The structure-activity relationship studies showed that the mols. containing a carbonyl group in the ninth position of the bicycle exhibited the maximum activity. Based on the exptl. and theor. results obtained, further directions for the development of this topic were proposed. This study involved multiple reactions and reactants, such as Ethyl 1,5-diphenyl-1H-pyrazole-3-carboxylate (cas: 17355-75-8Quality Control of Ethyl 1,5-diphenyl-1H-pyrazole-3-carboxylate<\/a>).<\/p>\n

Ethyl 1,5-diphenyl-1H-pyrazole-3-carboxylate (cas: 17355-75-8) belongs to pyrazole derivatives. The strategies for the synthesis of pyrazoles generally can be applied for the construction of indazoles. The presence of both electronegative nitrogen atoms in the pyrazole ring reduces the electron density of the C3- and C5-positions leaving electron density of C4-position unaltered. Thus the C4-position is vulnerable to electrophilic attack. The C3 electrophilic-position may undergo deprotonation in the presence of a strong base leading to ring opening.Quality Control of Ethyl 1,5-diphenyl-1H-pyrazole-3-carboxylate<\/a><\/p>\n
