A series of all novels 4(3-(4-Fluorophenyl)2-methyl-1-(4-(sulfonamidesubtituted)phenyl)-4-oxoazitidin-2-yl)-3-methyl-1-(p-tolyl)-1H-pyrazol-5(4H) One 5a-5r poly functionalized derivatives were containing sulfonamide functionality united with 2-Azitidinone (Azitidin-2-one or β-lactam) group which designed and synthesized with moderate to good yield. The starting with 4-acyl-2-pyrazolin-5-one (APYZ) 1 which condensed with different sulfonamides 2 produced intermediate Schiff bases 4-(arylideneamino)-N-(thiazol-2-yl)benzensulfonamide 3a-r were cyclization with 2-(4-flourophenyl)chloroacetylchloride (F-CAC) 4 which produced targeted compounds 5a-5r of 2-Azitidinone versatile group in good yield. The isolated compounds were recognized by spectral and elemental investigation. The compounds 5f, 5l, 5n, and 5r showed excellent increased antibacterial activity compared to streptomycin standard drug and 5c, 5f, 5l, 5o, and 5r showed moderate to good antioxidant properties with used DPPH radical scavenging assay.

The present includes the synthesis of pyrazoline derivatives using chalcones and phenyl hydrazine in the presence of ethanol. It also reveals that 2-pyrazoline complexes are physiologically active and may be used in a variety of therapeutic functions. FT-IR, ¹H-NMR, ¹³C-NMR, LC-MS, and elemental analyses were used to characterise newly synthesised phenyl-pyrazoline derivatives. The antimicrobial activity of the synthesised compounds was assessed using the agar well diffusion assay and the Minimum Inhibition Concentration (MIC). Compounds 4b, 4f, and 4h have exhibited remarkable antibiotic action against bacterial strains such as Staphylococcus aureus, Bacillus subtilis, Salmonella. Typhi, and Shigella sp. On the other hand, compound 4h had significant antifungal activity against Candida albicans and Aspergillus fusarium and was a highly promising agent when compared to standard nystatin.

Drug-resistant microorganisms are a serious problem, particularly when more strains become immune to different antimicrobials. Antibiotic resistance has now developed in several microbes. Therefore, it is crucial to build new medications that are still efficient. The amount of funding that is often available for such progress is lower than what is necessary. Kydia calycina is a Malvaceae flowering plant used in traditional Indian medicine to cure several diseases, including infections. The goal of this study was to determine whether K. Calycina has antifungal and antibacterial properties. Infections are caused by the profusion of microbes in the environment; thus, plant products and active chemicals are employed to assess the antimicrobial property of the extracts and the inhibition zone of each extract on a range of bacterial and fungal strains. The results showed that when it was applied to the species that were studied, there was a considerable decrease in the growth of bacteria. The plant was subjected to a phytochemical analysis, which was completed. This plant may be employed in the quest for bioactive natural substances that might be used as leads in the creation of pharmaceuticals. The antimicrobial mechanism of action was investigated by molecular docking, and it was determined that Hibiscoquinone B and Hibiscone C showed both antibacterial and antifungal activity.

Microbes generally develop resistance towards organic antibacterial agents like ampicillin, Sulfonamides, methicillin, etc., and progressively new drugs are being invented to replace them. Hence, replacement of organic antibacterial agents with inorganic analogues requires constant research and the present investigation reports alternatives for conventional antimicrobial agents like methylparaben, diazolidinyl urea, etc., in the cosmetic products with silver incorporated calcium borates. The chemically synthesized silver-calcium borates have been analyzed for phase purity using powder XRD analysis, nature of bonding using FTIR vibrations, and morphology using SEM. The antibacterial and antifungal studies were carried out for the novel inorganic silver-calcium borates incorporated cosmetic products. The products were also subjected to thermal & photostability studies and found to be comparable with that of commercially available products. A minimum quantity of 3 ppm of silver-calcium borate concentration was required to bring about nearly 100% bacterial reduction in the cosmetic products.

An efficient, three-component, catalyst free synthesis of dipyrazolo[1,5-a:3',4'-d]pyramid scaffolds has been carried out using 3-methyl-1H-pyrazol-5(4H)-one (1), 5-amino pyarazole (2a-b) and substituted aromatic aldehydes. The reaction underwent cyclocondensation reaction in reflux condition with moderate to good (62%–90 %) yields. The twenty newly prepared molecules were analyzed by means of 1H & 13C NMR, Mass, and IR spectroscopies and their activities against the bacterial and fungal strains were screened. Some of tested compounds have shown excellent antibacterial activities while another four were found to have good antifungal activity.
