Biochemical and Structural Studies of Protein Tyrosine Phosphatase PTP‐PEST (PTPN12) in Search of Small Molecule Inhibitors

Chemical Biology and Drug Design

PTP-PEST is considered an important drug target owing to its involvement in cancer progression and myocardial injury. Till now only a few inhibitors are currently being studied in the inhibition of PTP-PEST, majorly belonging to the class of metal-based drugs.

Synthesis and Investigation of Peptide–Drug Conjugates Comprising Camptothecin and a Human Protein‐Derived Cell‐Penetrating Peptide

Chemical Biology and Drug Design

ABSTRACT Drug targeting strategies, such as peptidedrug conjugates (PDCs), have arisen to combat the issue of off-target toxicity that is commonly associated with chemotherapeutic small molecule drugs. The PDCs crossed membranes and cleavable PDCs killed melanoma cells with nanomolar potency.

Scalable Thiol Reactivity Profiling Identifies Azetidinyl Oxadiazoles as Cysteine-Targeting Electrophiles

Covalent Modifiers

4c05711 Cysteine reactive groups are a mainstay in the design of covalent drugs and probe molecules, yet only a handful of electrophiles are routinely used to target this amino acid. Chatterjee, and Michael J. Bollong Journal of the American Chemical Society 2024 DOI: 10.1021/jacs.4c05711

Identification of a phenyl ester covalent inhibitor of caseinolytic protease and analysis of the ClpP1P2 inhibition in mycobacteria

Covalent Modifiers

Its role as a potential drug target for combating tuberculosis (TB) has just begun to be substantiated in drug discovery research. The knockdown also remarkably heightened the mutant's sensitivity to ethionamide and meropenem, but not to many other TB drugs.

Rational Design of CDK12/13 and BRD4 Molecular Glue Degraders

Covalent Modifiers

While molecular glue degraders exhibit drug-like properties, their discovery has traditionally been serendipitous and often requires post-hoc rationalization. In this study, we demonstrate the rational, mechanism-guided design of molecular glue degraders using gluing moieties.
