Stability-indicating HPTLC method for the simultaneous detection and quantification of alfuzosin hydrochloride, solifenacin succinate along with four of their official impurities

Stability and impurity profiling of new drug formulations are now receiving great attention in modern pharmaceutical analysis. In this work, a novel stability-indicating HPTLC coupled with densitometric quantification was developed for the simultaneous determination of alfuzosin (ALF) and solifenacin (SOL) along with their degradation products/official impurities. The two drugs were subjected to different stress conditions. ALF was liable to acidic and basic hydrolysis, while SOL was found to be susceptible to basic and oxidative degradation. The obtained degradation products, namely; ALF impurity-D and SOL impurities-A, E and I were then characterized by IR and mass spectrometry. Chromatographic separation was then performed on HPTLC silica plates 60 F254, as a stationary phase, using ethyl acetate: toluene: ethanol: ammonia (5: 2: 3: 0.4, by volume), as a mobile phase. The plates were scanned at 220 nm and visualized by iodine vapor in daylight. Effect of different factors, including the mobile phase composition and the detection wavelengths, were carefully studied to achieve the optimum conditions for chromatographic separation. Calibration curves were constructed over the ranges of 0.8 ? 30.0 mug/band for ALF and SOL, 0.5 ? 15.0 mug/band for ALF imp-D, 0.5 ? 4.0 mug/band for SOL imp-I and 0.75 ? 7.50 mug/band for SOL basic degradation. The method was also exploited for assessment of the two drugs? stability in Solitral capsules under accelerated storage conditions. The proposed method has many potentials of being simple, economic and selective making it an attractive procedure in analyzing not only the two cited drugs but also their impurities.

Reactivite du nitrite de sodium. V. Action sur les amino-acides, peptides et proteines

The action of sodium nitrite on various amino-acids was re-examined in conditions approximating to a biological medium. 13C-NMR provides evidence of the existence of intramolecular ring closures and the formation of 5-membered rings with ornithine, citrulline and arginine.The reaction of cystine shows the opening of the sulphur bridges, whereas cysteine leads to the formation of carboxy-thiiran and 3-sulpho-lactic acid.The hydrolysis of the amide bonds of asparagine and glutamine is complete whereas the peptides studied – carnosine and aspartam – do not undergo hydrolysis of the peptide linkage.However, the first deamination of glutathion (gamma-Glu-Cys-Gly) induces the peptide link to be broken and a cyclization with the formation of lactone to occur.A second deamination takes place on the cysteinyl residue released and allows the formation of a thiiran by intramolecular cyclization with the thiol group.The formation of thiiran was also observed with oxidized glutathion which has an S-S bridge.Finally, the formation of nitrosamines was detected by 15N-NMR during the reaction of sodium nitrite with two commercial products available to the general public.

Heteroalicyclic carboxamidines as inhibitors of inducible nitric oxide synthase; The identification of (2R)-2-pyrrolidinecarboxamidine as a potent and selective haem-co-ordinating inhibitor

Heteroalicyclic carboxamidines were synthesised and evaluated as inhibitors of nitric oxide synthases. (2R)-2-Pyrrolidinecarboxamidine, in particular, was shown to be a highly potent in vitro (IC50 = 0.12 muM) and selective iNOS inhibitor (>100-fold vs both eNOS and nNOS), with probable binding to the key anchoring glutamate residue and co-ordination to the haem iron.

Decarboxylative Anti-Michael Addition to Olefins Mediated by Photoredox Catalysis

Decarboxylative coupling of carboxylic acids with activated olefins has been accomplished using visible light photoredox catalysis. The strategic placement of a radical-stabilizing aromatic group at the beta-position of the olefin component biases the regioselectivity of the addition, allowing reliable, facile access to anti-Michael-type products from readily available precursors. The scope of this methodology was demonstrated with a range of carboxylic acids and appropriately substituted olefins and was applied toward a two-step synthesis of the antiarrhythmic agent encainide.
