Determination of doxazosin mesylate in tablets by RP-HPLC

Indian Journal of Pharmaceutical Sciences, 2011
A simple, precise and rapid RP-HPLC method was developed for the determination of doxazosin mesylate in pharmaceutical formulations. The method was carried out on a Chromolith RP-C(18) column using a mixture of potassium phosphate buffer and methanol (40:60 v/v) and detection was done at 251 nm. The linearity range was 1-5 μg/ml.

Photocaged Oxytocin and Vasopressin Probes to Decipher Neuropeptide Signalling With High Spatiotemporal Resolution

Angewandte Chemie International Edition, EarlyView.
Novel and biocompatible photoactivatable oxytocin and vasopressin probes, utilising state‐of‐the‐art photocages, remain inactive in the dark. Light exposure facilitates rapid spatiotemporal receptor activation and phospholipase C (PLC)‐mediated downstream signalling. Figure created in https://BioRender.com.

Nano‐Gs Protein Peptidomimetics: Rational Design of Gα C‐Terminus‐Derived Peptides Mimicking Key Components of Gs‐β2AR Interactions

Angewandte Chemie International Edition, EarlyView.
G protein‐coupled receptors (GPCRs) are major therapeutic targets. Modulating GPCR activity through intracellular sites is evolving. A structure‐ and computation‐assisted approach generated small G protein‐derived peptidomimetics targeting the intracellular binding crevice of the β2 adrenergic receptor mimicking features of the full G protein.
