A novel library of 1,3,4-thiadazoloaryl based pyrimidine-thiazole derivatives (10a-j) was synthesized and their chemical structures were confirmed by 1HNMR, 13CNMR, and mass spectral data. in silico ADME studies have demonstrated that all these compounds have a good pharmacokinetic profile. Further, these compounds were evaluated for their anticancer activity against a panel of human cancer cell lines such as prostate (PC3 and DU-145), lung (A549), and breast (MCF-7). The outcome results were compared with the standard reference as etoposide. Most of the tested compounds demonstrated remarkable anticancer activities, with IC50 values ranging from 0.01 ± 0.0017 µM to 23.6 ± 8.43 µM, where standard showed IC50 values from 1.97 ± 0.45 µM to 3.08 ± 0.135 µM, respectively. Particularly, these compounds 10a, 10b, 10c, 10d, 10e, and 10j displayed more prominent anticancer activities as etoposide. Molecular docking studies of the synthesized compounds were carried out against SARM (PDB ID: 3V49) and Abl-Tyrosine kinase (PDB ID: 1IEP), in which 10b and 10 h showed comparable dock scores of −7.3 and −7.5 against SARM (PDB ID: 3V49) and 10b and 10c −8.5 and −7.7 against Abl-Tyrosine kinase (PDB ID: 1IEP).

Nanotechnology has become the most effective and rapidly developing field in the area of material science, and silver nanoparticles (AgNPs) are of leading interest because of their smaller size, larger surface area, and multiple applications. The use of plant sources as reducing agents in the fabrication of silver nanoparticles is most attractive due to the cheaper and less time-consuming process for synthesis. Furthermore, the tremendous attention of AgNPs in scientific fields is due to their multiple biomedical applications such as antibacterial, anticancer, and anti-inflammatory activities, and they could be used for clean environment applications. In this review, we briefly describe the types of nanoparticle syntheses and various applications of AgNPs, including antibacterial, anticancer, and larvicidal applications and photocatalytic dye degradation. It will be helpful to the extent of a better understanding of the studies of biological synthesis of AgNPs and their multiple uses.

Objective: In this study, the isolation and identification of Exopolysaccharide (EPS) producing bacteria from polluted soil samples and its in vitro antioxidant activities were investigated. Methods: Isolation and identification of bacteria was investigating using 16 s rDNA genome sequencing method. Further, optimization (pH, time, and temperature), purification and characterization of EPS were performed using different (UV, FT-IR, C13-NMR and H1-NMR) methods. In addition, 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and hydrogen peroxide (H2O2) scavenging activities of EPS were performed. Results: The molecular characterization of isolated strain was confirmed as Bacillus aerophilus by 16S rDNA sequencing. The sequence was submitted to NCBI (Genbank accession number MH553072). Characterization of EPS by UV, FT-IR, C13-NMR and H1-NMR revealed the presence of hydroxyl, carbonyl, and carboxyl functional groups. SEM analysis of EPS showed a solid surface with an irregular shape. The optimum conditions for EPS production were pH 7.0, cultivation time 72 h (3.73 ± 0.211 g/L) and temperature 30 °C respectively. The yeast and sucrose extract showed higher EPS production. In addition, in vitro DPPH, H2O2 studies showed 56.6 and 67.5% of scavenging activity at 4 mg/mL of concentration. Conclusions: From this study, the novel EPS producing Bacillus aerophilus rk1 was identified. Further, the purified EPS showed good antioxidant activity.
