On February 28, 2022, Kalhor, Mehdi; Zarnegar, Zohre published an article.Quality Control of 4-Phenylthiazol-2-amine The title of the article was 1-Methylimidazolium ionic liquid supported on Ni@zeolite-Y: fabrication and performance as a novel multi-functional nanocatalyst for one-pot synthesis of 2-aminothiazoles and 2-aryl benzimidazoles. And the article contained the following:

In the present study, 1-methyl-3-(3-trimethoxysilylpropyl)-1H-imidazol-3-ium chloride-supported Ni@zeolite-Y-based nanoporous materials (Ni@zeolite-Im-IL) were synthesized and their structures were confirmed using different characterization techniques such as FT-IR, FE-SEM, EDX, XRD, BET and TGA-DTG analyses. In order to synthesize this multi-functional nano-system, zeolite-NaY was modified first, with exchanged Ni2+ ions and 3-chloropropyltriethoxysilane (CPTES) as a coupling reagent and then functionalized to imidazolium chloride ionic liquid by N-methylimidazole. New multi-functional nano-material of Ni@zeolite-Im-IL demonstrated high activity in the catalytic synthesis of 2-aminothiazoles 3a-l by one-pot reaction of methylcarbonyls, thiourea and iodine at 80°C in DMSO with good to excellent yields (85-98%). Also, the catalytic synthesis of 2-aryl benzimidazoles, 6a-m was performed by the condensational reaction of o-arylendiamine and aromatic aldehydes in EtOH at room temperature with excellent yields (90-98%). Advantages of this efficient synthetic strategy include higher purity and shorter reaction time, excellent yield, easy isolation of products, the good stability, activity and feasible reusability of the metallic ionic liquid nanocatalyst. These benefits have made this method more compatible with the principles of green chem. The experimental process involved the reaction of 4-Phenylthiazol-2-amine(cas: 2010-06-2).Quality Control of 4-Phenylthiazol-2-amine

And the article contained the following:

A series of novel N-[4-(substituted)-1,3-thiazol-2-yl]-2-(substituted)acetamides and Me 2-(2-(2-(substituted)acetamido)thiazol-4-yl)acetates were synthesized. All compounds were screened for their in vitro antibacterial activity against S. aureus, E. coli, P. aeruginosa, and K. pneumonia by disk diffusion and for antifungal activity against P. marneffei, T. mentagrophytes, A. flavus, and A. fumigatus by serial plate dilution Some of the compounds exhibited growth inhibition against all the tested bacterial strains, with MIC of 12.5-6.25 μg/mL. Among the compounds tested for antifungal activity, several of them showed a wide range of activity against all the tested strains. Most of the newly synthesized compounds were effective against fungal strains rather than bacterial strains. However, some of the compounds showed selective sensitivity against some of the bacterial strains, whereas they were unable to sustain the growth of other strains.
