Enantiodifferentiation of α-Arylacetic Acid and Thiohydantoin Derivatives by NMR Using Thiourea-Based Chiral Solvating Agents [PDF]

Molecules
Two thiourea-based chiral solvating agents (CSAs), S-1 and S-2, were evaluated for the enantiomeric discrimination of representative α-arylacetic acids by 1H NMR spectroscopy in the presence of DMAP. Enantiomeric discrimination was assessed by monitoring

Recent Applications of Hydantoins in Drug Discovery: Updates (2019~Present) [PDF]

Molecules
Hydantoins, exemplified by the imidazolidine-2,4-dione core, are privileged scaffolds in medicinal chemistry due to their compact structure, versatile hydrogen-bonding capacity, ability to fine-tune physicochemical properties for drug-like molecules, and

In vitro assays identified thiohydantoins with anti-trypanosomatid activity and molecular modelling studies indicated possible selective CYP51 inhibition [PDF]

Scientific Reports
This work investigates the anti-trypanosomal activities of ten thiohydantoin derivatives against the parasite Trypanosoma cruzi. Compounds with aliphatic chains (THD1, THD3, and THD5) exhibited the most promising IC50 against the epimastigote form of T ...

Macathiohydantoin L, a Novel Thiohydantoin Bearing a Thioxohexahydroimidazo [1,5-a] Pyridine Moiety from Maca (Lepidium meyenii Walp.)

Molecules, 2021
Five new thiohydantoin derivatives (1–5) were isolated from the rhizomes of Lepidium meyenii Walp. NMR (1H and 13C NMR, 1H−1H COSY, HSQC, and HMBC), HRESIMS, and ECD were employed for the structure elucidation of new compounds.

ANTITHYROID ACTIVITY OF THIOHYDANTOINS [PDF]

British Journal of Pharmacology and Chemotherapy, 1958
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.
