Synthesis of selective molecularly imprinted polymer for solid-phase extraction of glipizide by using a pseudo-template


ABSTRACT:

Selective molecularly imprinted polymers (MIPs) for solid-phase extraction and determination of glipizide have been designed and prepared. MIPs were synthesized with acrylamide as the functional monomer and ethyleneglycoldimethacrylate as the cross-linker in chloroform as a porogenic solvent by using bulk polymerization method. MIPs are able to bind 100% glipizide in chloroform by using a batch method compared to a non-imprinted one. By using Fourier Transform Infra Red, it was found that hydrogen bonding occurred between the carbonyl group of acrylamide and the proton donor of template. These results find the opportunity for this MIP to be used as an alternative of the pretreatment method before determination of glipizide by using glibenclamide as a pseudotemplate.

A Validated specific Stability-indicating RP-HPLC method for Aripiprazole and its related substances

Image
ABSTRACT : A validated specific stability indicating reversed-phase liquid chromatographic method was developed for the quantitative determination of Aripiprazole and its related substances in bulk samples, pharmaceutical dosage forms in presence of degradation products. Forced degradation studies were performed on bulk sample of Aripiprazole as per ICH prescribed stress conditions using acid, base, oxidative, thermal stress and photolytic degradation to show the stability indicating power of the method. Significant degradation was observed during basic stress and no degradation was observed in other stress conditions. The chromatographic method was optimized using the samples generated from forced degradation studies and the impurity spiked with Aripiprazole. Good resolution between the peaks corresponds to impuritiy-1, degradation products from the analyte were achieved on YMC PACK C18 column using the mobile phase consists a mixture of Sodium dihydrogen Orthophosphate dehydra...
