Structure-Based Optimization of Covalent, Small-Molecule Stabilizers of the 14-3-3?/ER? Protein–Protein Interaction from Nonselective Fragments

Covalent Modifiers

Here, we show the structure-based optimization of the nonselective fragment toward selective and highly potent small-molecule stabilizers of the 14-3-3σ/ERα complex. We have previously identified a disulfide fragment that stabilized the hub protein 14-3-3σ bound to several of its clients, including ERα and C-RAF.

Chemoselective Covalent Modification of K-Ras(G12R) with a Small Molecule Electrophile

Covalent Modifiers

While small molecule inhibitors for the G12C mutant have been successfully developed, allele-specific inhibition for other KRAS hotspot mutants remains challenging. An X-ray crystal structure reveals an imidazolium condensation product formed between the α,β-diketoamide ligand and the ε- and η-nitrogens of arginine 12.

Small Molecule of the Year – 2022

Drug Hunter

As a non-hormonal oral drug, YCT529 targets RARalpha , which is involved in both Vitamin A metabolism and sperm production, and appears to work tolerably and reversibly in preclinical studies. The post Small Molecule of the Year – 2022 appeared first on Drug Hunter. LP0200 has completed a Ph.

The unique reactivity profile of the 1,2-aminothiol moiety of N -terminal cysteines ( N -Cys) of proteins renders it highly attractive for regioselective protein labelling.

Interactions of small molecule inhibitors with secreted phospholipase A2: A review of the structural data

Chemical Biology and Drug Design

The products of sPLA 2 -catalysis (lysophospholipids and free fatty acids such as arachidonic acid) as well as secondary metabolites produced by the arachidonic acid cascade are mediators of inflammation and subsequent tissue injury.

Polyphyllin VII Enhances the Sensitivity of Prostate Cancer Cells to Docetaxel by Promoting Mitochondrial Dysfunction and Inducing Ferroptosis

Chemical Biology and Drug Design

Polyphyllin VII (PPVII), a small molecule natural product derived from the traditional herb Paris polyphylla, has shown anticancer potential. ABSTRACT Docetaxel (DTX) is the preferred chemotherapeutic drug for prostate cancer (Pca), but the emergence of resistance has significantly reduced its efficacy.

Unlocking the potential of natural products in drug discovery

Drug Target Review

Between 2000 and 2020, approximately 30 percent of the newly introduced small molecule drugs were derived from natural products. Why focus on natural products and phytochemicals? 3 This indicates there is a large pool of undiscovered natural products with therapeutic promise waiting to be mined.
