Dr. Nitya Anand was a leading figure in Indian pharmaceutical research. His career spanned several decades, during which he significantly contributed to advancement in drug development and public health. His innovation of Centchroman (Saheli), the world's first non-steroidal oral contraceptive pill, changes the course of contraception use in India. He had done groundbreaking work in leprosy treatment, synthetic peptides, and antibiotics. With over 400 publications and 130 patents, he supervised over 100 PhD students. His work has been recognized with many prestigious awards, including the Padma Shri and the National Nehru Science Award, which have left a long-lasting impact on medicinal chemistry and public health.

High-risk human papillomavirus E6 oncoprotein is a model system for the recognition and degradation of cellular p53 tumor suppressor protein. There remains a gap in the understanding of the ubiquitin transfer reaction, including placement of the E6AP catalytic HECT domain of the ligase concerning the p53 substrate and how E6 itself is protected from ubiquitination. We determined the cryoelectron microscopy (cryo-EM) structure of the E6AP/E6/p53 complex, related the structure to in vivo modeling of the tri-molecular complex, and identified structural interactions associated with activation of the ubiquitin ligase function.

The cholinergic deficits and amyloid beta (Aβ) aggregation are the mainstream simultaneously observed pathologies during the progression of Alzheimer's disease (AD). Deposited Aβ plaques are considered to be the primary pathological hallmarks of AD and are contemplated as promising diagnostic biomarker. Herein, a series of novel theranostic agents were designed, synthesised and evaluated against cholinesterase (ChEs) enzymes and detection of Aβ species, which are major targets for development of therapeutics for AD.

In this study, a Co doped polyhedral carbon skeleton (Co CN) was prepared by nitrogen carbonization using ZIF-67 as a precursor. The Co CN features a rough surface with excellent electrical conductivity, and the Co atoms exhibit unique catalytic properties. Based on these characteristics, we used Co CN as a carrier to load Au nanoparticles (NPs) onto its surface through the linkage and reduction effects of polyoxometalates (POMs).

The development of stable biopharmaceutical formulations, such as monoclonal antibodies, poses a great challenge in the pharmaceutical industry. This study investigated the stabilizing effect of 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) in liquid and solid formulations of infliximab during processing and storage. The solid formulation was produced by a scaled-up high-speed electrospinning method, resulting in a product suitable for reconstitution with excellent dissolution properties.
