Angewandte Chemie, Volume 134, Issue 11, March 7, 2022., 2022 A prebiotic synthesis of the nucleobase orotate, and the citric acid cycle intermediate pyruvate, proceeds in a single pot from two small glycine derivatives, hydantoin and glyoxylate, under mild aqueous conditions. These findings support a co‐evolution of pathways to core protometabolites and nucleic acid building blocks in a common environment ...

The Chemical Record, Volume 23, Issue 11, November 2023., 2023 Efforst are described for developing Brønsted base‐catalyzed, site‐ and stereoselective α‐functionalization of a variety of unsaturated enolizable carbonyl compounds via transient enolates featuring an extended π‐system. Abstract Chiral Brønsted base (BB) catalyzed asymmetric transformations constitute an important tool for synthesis.

A recent update on new synthetic chiral compounds with antileishmanial activity
Chirality, Volume 34, Issue 10, Page 1279-1297, October 2022., 2022 ∎ Abstract Parasitic diseases, including malaria, leishmaniasis, and trypanosomiasis, affect billions of people and are responsible for almost 500,000 deaths/year. In particular, leishmaniasis, a neglected tropical disease, is considered a global public health problem because current drugs have several drawbacks including to toxicity, high cost, and ...

Archiv der Pharmazie, Volume 355, Issue 5, May 2022., 2022 Structurally distinct enzalutamide‐based proteolysis‐targeting chimeras (PROTACs) were designed, synthesized, and biochemically analyzed. For the first time, androgen receptor degraders were evaluated in lung cancer cells, where significant degradation of the target was observed.

Heterocyclic systems containing S/N regioselective nucleophilic competition: Facile synthesis, antitubercular and antimicrobial activity of thiohydantoins and iminothiazolidinones containing the benzo [PDF]
Journal of the Serbian Chemical Society, 2005 The required compounds N-aryl-N'-(3-chloro-2-benzo[b]thenoyl)-thioureas 1a-k were prepared by condensing 3-chloro-2-benzo[b]thenoyl chloride with different arylamines using ammonium thiocyanate, which in turn when treated with chloroacetic acid, yielded ...

Synthesis and Biological Evaluation of Novel Dispiro-Indolinones with Anticancer Activity
Molecules, 2023 Novel variously substituted thiohydantoin-based dispiro-indolinones were prepared using a regio- and diastereoselective synthetic route from 5-arylidene-2-thiohydantoins, isatines, and sarcosine.

European Journal of Organic Chemistry, Volume 2021, Issue 41, Page 5649-5660, November 8, 2021., 2021 Intramolecularly hydrogen‐bonded analogues of the green fluorescence protein chromophore with an aminoimidazole moiety were synthesised and characterised. The fluorescence mechanism and substituent effects were investigated in a combined experimental‐computational approach, and a 279‐fold improvement in the quantum yield was realised.
