Structural, antioxidant, antiproliferative and in?silico study of pyridine-based hydrazonyl?selenazoles and their sulphur isosteres

To evaluate the impact of chalcogen atom type, we performed a comparative study of antioxidant capacity and antiproliferative activity of a focused library of three pyridine-based hydrazonyl-1,3-selenazoles and their sulfur isosteres in five antioxidant assays and in six human solid tumor cell lines, respectively. In-silico calculations were further used to check pharmacokinetic profiles of investigated compounds such as drug-likeness parameters and interaction with water. Generally, selenium compounds appear to be more potent in comparison to sulfur isosteres in the performed essays.

Synthesis of new Zn (II) complexes for photo decomposition of organic dye pollutants, industrial wastewater and photo-oxidation of methyl arenes under visible-light

Synthesis of new Schiff's base Zn-complexes for photo-oxidation of methyl arenes and xylenes are reported under visible light irradiation conditions. All the synthesized new ligands and Zn-complexes are thoroughly characterized with various spectral analyses and confirmed as 1:1 ratio of Zn and ligand with distorted octahedral structure. The bandgap energies of the ligands are higher than its Zn-complexes. These synthesized new Zn(II) complexes are used for the photo-fragmentation of organic dye pollutants, photodegradation of food industrial wastewater and oxidation of methyl arenes which are converted into its respective aldehydes with moderate yields under visible light irradiation. The photooxidation reaction dependency on the intensity of the visible light was also studied. With the increase in the dosage of photocatalyst, the methyl groups are oxidized to get aldehydes and mono acid products, which are also identified from LC-MS data. Finally, [Zn(PPMHT)Cl] is with better efficiency than [Zn(PTHMT)Cl] and [Zn(MIMHPT)Cl] for oxidation of methyl arenes is reported under visible-light-driven conditions.

Study of in vitro biological activity of thiazoles on Leishmania (Leishmania) infantum

Objectives: In the prospection of possible agents against neglected diseases, thiazole compounds are presented as promising candidates and are known to have activity against trypanosomatid parasites. Thus, this work aimed to evaluate the effects of thiazo

Synthesis, anti-HIV activity, molecular modeling study and QSAR of new designed 2-(2-arylidenehydrazinyl)-4-arylthiazoles

Taking into consideration the eminence of 1,3-thiazoles in medicinal chemistry and in a view of procuring more pronounced biological contour, the synthesis of 2-(2-arylidenehydrazinyl)-4-arylthiazoles 6–43 was made possible by the cyclization reaction of thiosemicarbazones and α-bromoacetophenones. The thiosemicarbazones 5a-m were in turn synthesized from substituted benzaldehydes or acetophenones and thiosemicarbazide. Optimization of the reaction conditions was carried out in order to attain the target molecules in good yields. All the new compounds were evaluated in vitro for their antiviral activity against the replication of HIV-1 and HIV-2 in MT4 cells using a MTT assay. Screening results indicated that compounds 32–34 are the only compounds in the series inhibiting HIV-1 and HIV-2 replication in cell cultures with IC50 of >2.71, >2.19 and > 1.71 μM, respectively. The molecular docking of compounds 32 and 34 with some amino acids of human immunodeficiency virus reverse transcriptase (HIV RT) were also studied. The preliminary quantum structure-activity relationship (QSAR) among the newly synthesized congeners was obtained by two methods, Multiple Linear Regression (MRL) and Genetic Function Approximation (GFA).

Study of oxidative cyclization using PhI(OAc)2 in the formation of benzo[4,5]thiazolo[2,3- C ][1,2,4]triazoles and related heterocycles - Scope and limitations

A one-pot, two-step reaction for the synthesis of benzo[4,5]thiazolo[2,3-c] [1,2,4]triazoles and related heterocycles under mild conditions was herein developed. The key step of this transformation is an oxidative cyclization employing PhI(OAc)2/sub
