Abstract:

Aminomethylation (i.e.Mannich reaction) of benzimidazole was carried out by treating benzimidalzole with formaldehyde and 4-aminosalicylic acid. The resultant compound was designated as 1-(4-carboxy-3-hydroxyphenyl aminomethyl) benzimidazole (BI-SA). The transition metal complexes of Cu2+, Co2+, Ni2+, Mn2+, Zn2+and Fe3+of BI-SA have been prepared and characterized by elemental analyses, spectral studies, magnetic moment determination, molar conductivity measurement and microbicidal activity.

Abstract:

Two formaldehyde-based terpolymeric resins (anthranilic acid-catechol-formaldehyde (ACF) and salicylic acid-catechol-formaldehyde (SCF)) have been synthesized by condensing anthranilic acid with catechol and salicylic acid with catechol at 80 ± 5°C using dimethylformamide as a solvent. The resins were characterized by spectral analysis using Fourier-transform infrared (FTIR) spectroscopy. The physical-chemical properties of the resins have been studied. The exchange behavior of various metal ions, namely, Cd2+, Cr3+, Ca2+, and Mg2+, towards the synthesized resins has been studied depending on

We present a study of salicylic acid and its hydrates, with up to four water molecules, done by employing chirped-pulse Fourier transform microwave spectroscopy. We employed the spectral data set of the parent, 13C, and 2H isotopologues to determine the molecular structure and characterize the intra- and intermolecular interactions of salicylic acid and its monohydrate. Complementary theoretical calculations were done to support the analysis of the experimental results. For the monomer, we analyzed structural properties, such as the angular-group-induced bond alternation (AGIBA) effect. In the

Proteins undergo continuous changes under the action of various intrinsic and extrinsic factors, leading to alteration of several intracellular metabolic pathways and the development of various clinical disorders. Non-enzymatic glycosylation is one of the main factors responsible for the progression of diabetic complications and the aging process. Although there are currently many effective therapies in the prevention and treatment of these diseases, in the last decade, there has been an increasing trend of replacing synthetic drugs by natural compounds, in order to reduce the side effects tha

Confirmation of the adsorption of the salicylic acid molecule and the formation of a salicylic acid–MXene complex were determined by experimental SERS-based spectral observations such as greatly enhanced out-of-plane bending modes of salicylic acid at 896 cm−1 and a band doublet at 681 cm−1 and 654 cm−1.

Summary Salicylic acid is a phytochemical with beneficial effects on human well-being. Salicylic acid is a phenolic compound and is present in various plants where it has a vital role in protection against pathogenic agents. Natural sources include fruits, vegetables and spices. The most famous and defined effect of salicylic acid is prostaglandin synthesis inhibition. Salicylic acid has antiinflammatory effects through suppression of transcription of genes for cyclooxygenase. Most of the pharmacological properties of salicylic acid can be contributed to the inhibition of prostaglandin synthes

To assess the role of nonionic diffusion of salicylic acid (pKa = 3) in the terminal nephron, we measured the passive permeability of [14C]salicylic acid in rabbit cortical collecting ducts isolated and perfused in vitro. This segment can produce and maintain a maximal pH gradient between blood and tubular fluid. When peritubular pH was kept constant at pH 7.4 the apparent permeability of salicylic acid (P', 10(-6) cm/s) was 6.2 +/- 1.1 at a luminal pH of 6.0, 17.2 +/- 5.3 at a luminal pH of 5.5, and 39.0 +/- 4.7 at a luminal pH of 5.0.
