Development of paroxetine loaded nanotransferosomal gel for intranasal delivery with enhanced antidepressant activity in rats.

The aim of this study was to develop paroxetine (PXT) loaded nanotransferosomal gel (PXT-NTFG) for intranasal brain delivery. The process involved fabricating PXT-NTFs (paroxetine-loaded nanotransferosomes) through a thin film hydration method and optimizing them based on parameters such as particle size (PS), zeta potential (ZP), polydispersity index (PDI), and entrapment efficiency (EE). The optimized PXT-NTFs exhibited uniform morphology with a PS of 158.

Molecular modelling and antimicrobial activity of newly synthesized benzothiazolo[3,2-]pyrimidine clubbed thiazole derivatives.

A series of benzothiazolopyrimidine-thiazole conjugates , , and were produced through the reactions of 8-acetylbenzothiazolopyrimidine-thiosemicarbazone compound with chloroacetone, (un)substituted phenacyl chlorides, and ethyl chloroacetate, respectively. Based on DFT study, the synthesized conjugates had a twisted shape, except for the parent benzothiazolopyrimidine and its thiosemicarbazone compound , which were flat. The study of FMO's also showed that the substituted thiazole derivatives and have equivalent configurations of HOMO and LUMO, as well as exhibiting the least FMO's gap (ΔE).

Formulation and statistical optimization of letrozole loaded nanotransferosomal gel for tumor targeting.

Letrozole (LTZ) is used as first-line treatment for hormone-positive breast cancer (BC) in postmenopausal women. However, its poor aqueous solubility and permeability have reduced its clinical efficacy. Herein, we developed LTZ-nanotransferosomes (LTZ-NT) to address above mentioned issues.

Derivative spectroscopy and wavelet transform as green spectrophotometric methods for abacavir and lamivudine measurement.

Herein, two different sustainable and green signal processing spectrophotometric approaches, namely, derivative spectroscopy and wavelet transform, have been utilized for effective measurement of the antiretroviral therapy abacavir and lamivudine in their pharmaceutical formulations. These methods were used to enhance the spectral data and differentiate between the absorption bands of abacavir and lamivudine in order to accurately measure their concentrations. For determining abacavir and lamivudine, the first derivative spectrophotometric method has been applied to the zero-order and ratio spectra of both drugs.

A fluorescence chemo sensor approach for determination of finerenone in pharmaceutical formulation and human plasma: Method development and validation.

Finerenone, a non-steroidal mineralocorticoid receptor antagonist, has gained recent approval for treating cardiovascular and kidney-related conditions. Herein, an innovative fluorescence chemo sensor was developed for the determination of finerenone in the pharmaceutical dosage form and the plasma matrix. The method is basically based on chemical transformation of finerenone into a fluorescent product through sequential reactions.
