A review. Inappropriate or excessive pulmonary inflammation can contribute to chronic lung diseases. In health, the resolution of inflammation is an active process that terminates inflammatory responses. The recent identification of endogenous lipid-derived mediators of resolution has provided a window to explore the pathobiol. of inflammatory disease and structural templates for the design of novel pro-resolving therapeutics. Resolvins (resolution-phase interaction products) are a family of pro-resolving mediators that are enzymically generated from essential omega-3 polyunsaturated fatty acids. Two mol. series of resolvins have been characterised, namely E- and D-series resolvins which possess distinct structural, biochem. and pharmacol. properties. Acting as agonists at specific receptors (CMKLR1, BLT1, ALX/FPR2 and GPR32), resolvins can signal for potent counter-regulatory effects on leukocyte functions, including preventing uncontrolled neutrophil swarming, decreasing the generation of cytokines, chemokines and reactive oxygen species and promoting clearance of apoptotic neutrophils from inflamed tissues. Hence, resolvins provide mechanisms for cytoprotection of host tissues to the potentially detrimental effects of unresolved inflammation. This review highlights recent exptl. findings in resolvin research, and the impact of these stereospecific mols. on the resolution of pulmonary inflammation and tissue catabasis.

Mikhailova, T. A. published the artcilePolarographic study of some nitrogen-containing heterocycles, COA of Formula: C10H14N2O, the publication is Zhurnal Obshchei Khimii (1969), 39(1), 26-30, database is CAplus.

Polarographic halfwave potentials were reported in the pH range of 1.85-11.6 for pyridine, quinoline, acridine, their 4-carboxylic acids, and the amides of these acids with N-CHMeCH2Ph grouping. Also included were data on N-(1-methyl-2-phenylethyl)amides of isonicotinic acid with the following 2,6-ring substituents: H, H; Cl, Cl; MeO, MeO; Et2N, Et2N; Cl, MeO; Cl, Et2N. N,N-diethylisonicotinamide with the following 2,6-substituents were also reported: H, H; Cl, Cl; Cl, MeO; MeO, MeO; Cl, Et2N; Et2N, Et2N. The main center of reaction in these compounds is the C:N link which gives the 1st polarographic wave at any pH value. Introduction of 4-substituents with electron-acceptor properties serves to lower the halfwave potential; introduction of electron donor groups in 2,6-positions raises the halfwave potential. The CO2H and CONHR groups cause a 2nd polarographic wave in neutral medium only. Treating the acyl chloride with Et2NH in C6H6 gave the diethylamides of: isonicotinic acid, b3 133°, n20D 1.5238; 2,6-dichloroiso-nicotinic acid (I), m. 82-4°; 2-chloro-6-methoxy analog, b3 153°; and the 2,6-dimethoxy analog, m. 87-8°. Heating the diethylamide of I with Et2NH at 100° 1 day gave the diethylamide of 2-chloro-6-diethylaminoisonicotinic acid, b4 182-4°; similarly, by heating 26 hrs. at 200°, the 2,6-bis(diethylamino)analog, m. 54-6°, b3 185-7°, was prepared

Santhosh, Akhil published the artcileRandomized double-blind, placebo-controlled study of topical diclofenac in the prevention of hand-foot syndrome in patients receiving capecitabine (the D-TORCH study), SDS of cas: 169590-42-5, the publication is Trials (2022), 23(1), 420, database is CAplus and MEDLINE.

Abstract: Introduction: Hand-foot syndrome (HFS) is a common cutaneous side effect of capecitabine therapy. Apart from oral cyclooxygenase-2 (COX-2) inhibitor (celecoxib), there are no proven strategies for the prevention of HFS. However, celecoxib is associated with significant cardiotoxicity. To date, no study has evaluated the role of topical COX inhibitor, diclofenac. In this study, we aim to compare topical 1% diclofenac gel with placebo in the prevention of capecitabine-induced HFS. Methods: This is a randomized, placebo-controlled, double-blind, parallel-group superiority trial: the Diclofenac Topical in Reducing Capecitabine induced HFS (D-TORCH) study. A total of 264 patients with breast and gastrointestinal malignancies will be randomly allocated (stratified by sex and type of therapy [monotherapy or combination regimen with capecitabine]) to receive either 1% topical diclofenac or placebo that will be applied over the palmar and dorsal surface of the hands twice daily while taking capecitabine for 12 wk. The patients will be followed up until the end of four cycles. The primary objective of this study is to compare the effect of topical diclofenac with placebo in preventing HFS (incidence of NCI CTCAEv5.0 grade 2 or higher HFS). The secondary objective is to compare the effect of topical diclofenac with placebo on preventing all grades of HFS (incidence of NCI CTCv5.0 all grade HFS), time to develop HFS (from the start of capecitabine), patient-reported outcomes (PROs) (HF-HRQoL questionnaire), adherence with the application (self-reported), capecitabine dose changes (number of patients with dose modifications due to HFS) and safety profile (NCICTCv5.0 all grade HFS) Discussion: The D-TORCH study aims to determine if 1% topical diclofenac reduces the incidence of grade 2 or higher HFS in patients receiving capecitabine. To date, there have been a lot of trials for hand-foot syndrome prevention using agents like pyridoxine, vitamin E, carvedilol, and various polyherbal formulations, but none has been found successful. If the trial meets the primary end point, 1% topical diclofenac will be the new standard of care for HFS prevention. Trial registration: Clin. Trials Registry of India CTRI/2021/01/030592. Prospectively registered on Jan. 19, 2021

Bronsted acid-promoted palladium(II)-catalyzed regioselective installation of halogens (Br, Cl, and I) to the aromatic ring of benzamide derivatives to afford the halogenated arenes I [R = H, 4-Me, 5-Cl, etc.; X = Cl, Br, I] was achieved using primary amides. Mild reaction conditions, use of primary amide as a directing group, external additive-free conditions and gram-scale reaction were some appealing features of this protocol.
