Abstract:
Salicylic acid is currently of little use, but its derivatives are one of the most large-tonnage drugs in the world. However, the natural sources of salicylic acid cannot satisfy the needs for its preparations and therefore the acid and its derivatives are obtained exclusively by synthetic means. Derivatives of salicylic acid are of great interest, due to their high reactivity and widespread use in medical practice as anti-inflammatory, antipyretic, analgesic, antimicrobial, antiseptic and anti-tuberculosis drugs. Currently, there is a fairly large body of data on the synthesis, structure, and

Abstract:
The antifungal activity of anacardic acid and two of its derivatives was tested against some plant pathogenic fungi and the inhibitory effect was compared with that of salicylic acid. Anacardic acid was found to be most effective and it inhibited Colletotrichum capsici spore germination at 125–150 μg mL−1. The results suggest that salicylic acid with appropriate structural modifications may prove to be a superior antifungal agent and can be utilized in controlling certain plant diseases under field conditions.

Abstract:
Synthesis of flavanone-6-carboxylic acid derivatives had been conducted via the route of chalcone. The synthesis was carried out from salicylic acid derivative, i.e. 4-hydroxybenzoic acid, via esterification, Fries rearrangement, Claisen-Schmidt condensation and 1,4-nucleophilic addition reactions. 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

Pharmaceuticals such as salicylic acid are commonly detected in wastewater and surface waters, increasing concern for possible harmful effects on humans and the environment. Their difficult removal via conventional treatments raised the need for improved strategies, among which the development of bioderived adsorbents gained interest because of their sustainability and circularity. In this work, biobased cross-linked adsorbents, synthesized via a sustainable approach from starch derivatives, namely beta-cyclodextrins and maltodextrins, were at first characterized via FTIR-ATR, TGA, SEM, and el

ABSTRACT. The versatile scaffold, N'-(2-cyanoacetyl)-2-hydroxybenzohydrazide (3) was utilized in the production of new pyridine, chromene and thiazole derivatives as antimicrobial and antioxidant agents. The synthetic strategy involves the treatment of precursor 3 with various arylidene-malononitrile and 3-aryl-2-cyanoacrylate compounds to furnish substituted pyridines 5 and 7. The interaction of 3 with salicylaldehyde and/or phenyl isothiocyanate followed by cyclization with chloroacetone produced the corresponding 2-imino-2H-chromene-3-carbohydrazide and (thiazol-2-ylidene-acetyl)-salicylic

The aim of this study was to determine the types of UV filters used in adult and children’s sunscreen products sold in Poland (part of the EU market) and their frequency of use. The INCI compositions of sunscreen products were collected and analyzed for the presence of UV filters. The study included 150 randomly selected preparations for adults (from 71 brands) and 50 for children (from 33 brands). The survey concerned the UV filters listed in Annex VI to Regulation (EC) No 1223/2009 of the European Parliament and Council of 30 November 2009 on cosmetic products. The most frequently used UV fi

Abstract:
Benzimidazole, a heterocyclic compound with versatile biological activity, serves as a scaffold for medicinal chemistry. We aimed to develop new derivatives with anti-inflammatory and anti-bacterial effects. The design was done using software tools, followed by synthesis, isolation, purification and characterization of two derivatives. The two novel derivatives are synthesized by the reaction of benzimidazole with 5-sulphosalicylic acid (BM 1) and 3,5-dinitro salicylic acid(BM 2). Biological activity was evaluated using protein denaturation and agar well diffusion method. The results showed th

Abstract:
A method of oxidative mineralization of the salicylic acid and its derivatives as well as medicinal products containing salicylic acid as the active ingredient was investigated. Destruction of the organic compounds is possible both in the electrolyte under the oxidant, electrochemically formed in situ in the sulphuric acid solutions, and at the anode so. Simultaneously, at the cathode, reduction of the zinc ions, contained in a number of medicinal products, is possible. Final products of the oxidation are simple non-toxic organic compounds, carbon dioxide, and water. This process is the most e
