ANTITHYROID ACTIVITY OF THIOHYDANTOINS [PDF]
The antithyroid activity of 2‐thiohydantoin and some derivatives has been measured in rats, after a single dose and, also, after daily administration for 6 weeks. 2‐Thiohydantoin and its 5‐alkyl derivatives from 5‐methyl to 5‐sec‐butyl‐ showed considerable antithyroid activity at a dose of 0.05 m.mole/kg.

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 ...

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 new strategy has been proposed for the synthesis of an array of imidazo[5,1‐c][1,4]oxazine chemotypes by using a planned aza‐Michael addition in a 3‐CR heteroring‐forming, post‐cyclization transformation followed by an intramolecular fused‐heterocycles formation process.

A recent update on new synthetic chiral compounds with antileishmanial activity
∎ 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 ...

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.

Aldol Reactions of Conformationally Stable Axially Chiral Thiohydantoin Derivatives. [PDF]
Two novel axially chiral ortho-trifluoromethylphenyl thiohydantoin derivatives have been prepared atroposelectively from the reaction of R and S alanine methyl ester HCl salts with ortho-trifluoromethylphenyl isothiocyanate in the presence of triethyl ...

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.
