Most variants of bacteria are resistant to traditional antibiotics which are organic. To overcome the growing infections, bacteria resistant infections, and multiple drug resistance (MDR) rates, transition metals with biological importance were coordinated to organic ligands (Ibuprofen and Salicylic acid) with anti-inflammatory properties. In this study, metal complexes of mixed Ibuprofen and Salicylic acid were prepared using a standard method to give of the type [M(Ibu)(Sal)X] (where M = Fe2+, Ni2+, Cu2+, and X = Cl2, Ibu = Ibuprofen, Sal = Salicylic acid).

Abstract In this study, the removal of salicylic acid (SA) in water by ozone (O3) and ultraviolet/ozone (UV/O3) processes was investigated. Results showed that more than 50% of SA (10 mg/L) could be effectively removed after 1 min during these two processes. However, the UV/O3 process was much more effective than the O3 process for SA mineralization, and the total organic carbon reduction after 30 min was 69.5% and 28.1%, respectively. In the two processes, the optimum pH value for SA removal was 4.3, while that for SA mineralization was 10.0. Both bicarbonate and dissolved organic carbon sign

Sunscreens reduce the occurrence risk of skin disorders such as sunburn, skin aging, and cancer through their ability to absorb, reflect, and scatter ultraviolet (UV) radiation. This review provides an overview of UV filters as active ingredients of sunscreen products, emphasizing their classification and structural characteristics. Their photostability, mechanism of action of ultraviolet radiation absorption, optical properties, and regulatory status are discussed based on their chemical structure. The main classes of organic UV filters presented include aminobenzoic acid derivatives, salicyl

Early skin aging is a major and widespread aesthetic issue in today's society. Early skin aging can be caused by a number of factors, such as UV radiation exposure, oxidative damage to epidermal cells brought on by a poor diet or sedentary lifestyle, etc. Minerals, tannins, polyphenols, carotenoids, fatty acids, and vitamin C are all abundant in rose hip fruit. These nutrients are crucial for lowering oxidative stress and giving skin and dermal cells all the components they need.

Structure elucidation of products was performed using FT-IR, 1H-NMR, GC-MS and UV-Vis spectrometers. Reaction of 4-hydroxybenzoic acid with methanol catalyzed with sulfuric acid produced methyl 4-hydroxybenzoate in 87% yield. The acid-catalyzed-acetylation of the product using acetic anhydride gave

Abstract. The effect of Au, Ag & Cu (1 wt%) photodeposition onto CdS nanorod (length ~ 116 nm, aspect ratio = 21, surface area = 81 m2/gm) has been studied by photocatalytic degradation of 0.5 mM salicylic acid both under direct sunlight and UV (125 W Hg arc lamp, 10.4 mW/cm2) irradiation. The bare CdS nanorod (NR) exhibited higher photoactivity as compared to low activity of bare CdS (~10 nm) nanosphere (NS) and Au & Ag photodeposition highly improved the CdS nanorod photoactivity compared with Cu deposition. The fluorescence emission of CdS nanorod at 479 nm is also quenched due to m

Increased ultraviolet-B (UV-B) due to global change can affect plant development and metabolism. Quinoa tolerates extreme conditions including high UV levels. However, the physiological mechanisms behind its abiotic stress tolerance are unclear, especially those related to UV-B. We previously demonstrated that 9.12 kJ m−2 d−1 may induce UV-B-specific signaling while 18.24 kJ m−2 d−1 promotes a UV-B-independent response. Here, we explored the effects of these UV-B doses on hormonal regulation linked to plant morphology and defense among diverse varieties. Changes in fluorescence parameters of p

Rice plants contain high basal levels of salicylic acid (SA), but some of their functions remain elusive. To elucidate the importance of SA homeostasis in rice immunity, we characterized four rice SA hydroxylase genes (OsSAHs) and verified their roles in SA metabolism and disease resistance. Recombinant OsSAH proteins catalyzed SA in vitro, while OsSAH3 protein showed only SA 5-hydroxylase (SA5H) activity, which was remarkably higher than that of other OsSAHs that presented both SA3H and SA5H activities. Amino acid substitutions revealed that three amino acids in the binding pocket affected SA
