ALFA-HYDROXIMINO KETONES -- 1,2,3-TRIAZOLES -- ALLOBETULONE
Аннотация: Lupane and 18αH-oleanane α-hydroximino ketones were used to synthesize derivatives condensed at ring A with a substituted azole fragment, namely, C(2)-C(3)-fused oxazoles and 1,2,3-triazoles. Triterpene isoxazoles fused at the C(1)-C(2) bond are described for the first time. An optimized method was proposed for the synthesis of unsubstituted 1,2,3-triazoles, displaying cytotoxic activity (IC50 8.4-40.7 μM) relative to rhabdomyosarcoma, lung carcinoma, and MS melanoma cell lines.

ENAMINES -- ISOXAZOLES -- HYDROXAMOYL CHLORIDES
Аннотация: 2-(1,2,3-Thiadiazol-5-yl)enamines and 3-(1,2,3-triazol-4-yl)enaminones react with arylhydroxamoyl chlorides at room temperature with the exclusive formation of 3-aryl-4-(1,2,3-thiadiazol-5-yl)- and [4-(1,2,3-triazol-4-yl)carbonyl]isoxazoles in high yields. The proposed mechanism includes in situ generation of nitrile oxides, which participate in the (3+2)-dipolar cycloaddition reactions leading to the formation of the isoxazole ring.

Аннотация: Reactions of tetra-and pentafluorobenzoyl isothiocyanates with aminoazoles and aminoazines led to the formation of fluorinated 1,3-benzothiazin-4-ones which reacted with cyclic amines in different ways. Replacement of the N=C=S fragment was observed in some reactions of polyfluorobenzoyl isothiocyanates with nucleophiles.

    Blue-light-promoted radical c-h azolation of cyclic nitrones enabled by selectfluor® / A. A. Akulov, M. V. Varaksin, A. N. Tsmokalyuk [et al.] // Green Chemistry. - 2021. - Vol. 23, № 5. - P2049-2057

Аннотация: An original approach to achieve the C(sp2)–H azolation of cyclic aldonitrones mediated by Selectfluor® has first been employed. By exploiting a metal-free, visible-light-promoted cross-dehydrogenative C–N coupling reaction between model aldonitrones, 2H-imidazole 1-oxides, and NH-containing azoles, a series of novel azaheterocyclic derivatives have been obtained in yields up to 94%. The elaborated protocol has proved to be appropriate for gram-scale processes and displayed potential for utilization in the synthesis of novel structural analogues of lanabecestat. Besides, mechanistic studies have revealed that this coupling reaction is likely to proceed via a nitroxide-involving radical pathway, encompassing a chain of electron transfer events, such as hydrogen atom transfer (HAT) and single electron transfer (SET).

    Bis(azolyl)sulfonamidoacetamides: Synthesis and bioassay / P. S. Sankar, K. N. Babu, V. N. Padmavathi [et al.] // AIP conference proceedings. - 2022. - Vol. 2390. - Ст. 020021

ANTIMICROBIALS -- BIOASSAYS -- ANTIFUNGAL
Аннотация: Azole derivatives are valuable precursors in pharmacological arena. In fact, oxazole, thiazole and imidazole containing scaffolds display a variety of biological activities such as antitumor,1 antibacterial,2 antiviral,3 antioxidant,4,5 anti-inflammatory6 and antifungal7 activities. Azoles are also prominant molecules in various biochemical and synthetic transformations. Based on the importance of these heteroaromatics and also our interest to link the heterocycle molecules with a variety of functional groups we have synthesized a new class of bis(azolyl)sulfonamide acetamides from azolylsulfonylamines and azolylchloroacetamides in the presence of DMAP under ultrasonication and studied their antimicrobial activity. The compounds chloro substituted bis(thiazoles) (6c) and chloro substituted imidazolyl thiazoles (7c) displayed excellent antibacterial activity against B. subtilis greater than the standard drug, Chloramphenicol. Whereas 7c also showed excellent antifungal activity on A. niger higher than the standard drug, Ketoconazole.

CHEMICAL COMPOUNDS -- PHARMACEUTICALS -- ANTIMICROBIALS
Аннотация: Amide unit is a privileged structural motif and is a constituent of proteins, natural products and pharmaceuticals. Amongst different heterocyclic scaffolds, azoles and pyrimidines are the prominent entities in pharmaceutical arena. The biopotency of these heterocycles have triggered to synthesize a variety of heteroaromatics – azoles linked with pyridines by amino acetamide group. The target molecules-azolylaminoacetamidopyrimidines were prepared by the reaction of methyl azolylglycinate with pyrimidinyl-2-amine in the presence of DMAP and triethylamine in dichloromethane under ultrasonication. The lead molecules were evaluated for antimicrobial activity. Nitro substituted 2-((4-(4-chlorofuran-2-yl)thiazole-2-yl)amino)-N-(4,6-diphenylpyrimidin-2-yl)acetamide (9c) displayed excellent antibacterial activity against B. subtilis greater than the standard drug Chloramphenicol. However, 9c and nitro substituted 2-((4-(4-chlorofuran-2-yl)-1H-imidazol-2-yl)amino)-N-(4,6-diphenylpyrimidin-2-yl)acetamide (10c) showed antifungal activity on A. niger greater than the standard drug Ketoconazole.
