In 2022,Taha, Muhammad; Ahmad Khan, Aftab; Rahim, Fazal; Imran, Syahrul; Salahuddin, Mohammed; Uddin, Nizam; Mohammed Khan, Khalid; Adnan Ali Shah, Syed; Zafar, Ameeduzzafar; Amiruddin Zakaria, Zainul published an article in Arabian Journal of Chemistry. The title of the article was 《Synthesis of new 1,2-disubstituted benzimidazole analogs as potent inhibitors of β-Glucuronidase and in silico study》.SDS of cas: 622-95-7 The author mentioned the following in the article:
New benzimidazole analogs I were synthesized and characterized through different spectroscopic techniques such as 1H NMR, 13C NMR and HREI-MS. All analogs were screened for β-glucuronidase inhibitory potential. All analogs showed varied degree of inhibitory potentials with IC50 values ranging between 1.10 ± 0.10 to 39.60 ± 0.70μM when compared with standard D-saccharic acid-1,4- lactone having IC50 value 48.30μM. Analogs I [R1 = 2,5-dichlorophenyl, R2 = 4-nitrobenzyl], I [R1 = 4-chlorophenyl, R2 = 2,4-dichlorobenzyl], I [R1 = 4-nitrophenyl, R2 = 4-nitrobenzyl], I [R1 = 4-chlorophenyl, R2 = 4-nitrobenzyl], I [R1 = p-tolyl, R2 = 4-nitrobenzyl] and I [R1 = 4-chlorophenyl, R2 = 4-chlorobenzyl] having IC50 values 1.10 ± 0.10, 1.70 ± 0.10, 2.30 ± 0.10, 5.30 ± 0.20, 6.20 ± 0.20 and 8.10 ± 0.20μM resp., showed excellent β-glucuronidase inhibitory potential many folds better than the standard All other analogs also showed good inhibitory potential better as compared to standard Structure activity relationships (SAR) had been established for all compounds The results from mol. docking studies supports the established SAR and developed a strong correlation with the results from in to vitro assay. The mol. docking results clearly highlighted how substituents like nitro and chloro affect the binding position of the active compounds in the active site. The docking results were also used to properly establish the effect of bulky substituents of least active compounds on reduced β-glucuronidase inhibitory activity. Compounds I [R1 = Ph, p-tolyl, 3-methoxyphenyl; R2 = 4-methoxybenzyl, 4-bromobenzyl, 4-methylbenzyl, etc] were found non-toxic. In the experimental materials used by the author, we found 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7SDS of cas: 622-95-7)
1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7) is a useful reagent for the preparation of panicinotam derivatives for use as anti-inflammatory agents or immunomodulators.SDS of cas: 622-95-7 It can be synthesized by reacting 4-chlorobenzyl alcohol with bromodimethylsulfonium bromide (BDMS) It can also be synthesized by refluxing a mixture of 4-chlorobenzaldehyde, chlorotrimethylsilane, 1,1,3,3-tetramethyldisiloxane and lithium bromide.
