Some new 2-carbamoylmethylthio- and 2-(omega-dimethylamino-alkyl)thio-3-aryl-7-chloro-4(3H)-quinazolinones have been prepared from 2-thio-3-aryl-7-chloro-4(3H)-quinazolinones as the key intermediate. Five of the synthetic compounds were screened for their CNS activities on mice and found to be either CNS depressants or stimulants.

UI	MeSH Term	Description	Entries
D011799	Quinazolines	A group of aromatic heterocyclic compounds that contain a bicyclic structure with two fused six-membered aromatic rings, a benzene ring and a pyrimidine ring.	Quinazoline
D002491	Central Nervous System Agents	A class of drugs producing both physiological and psychological effects through a variety of mechanisms. They can be divided into "specific" agents, e.g., affecting an identifiable molecular mechanism unique to target cells bearing receptors for that agent, and "nonspecific" agents, those producing effects on different target cells and acting by diverse molecular mechanisms. Those with nonspecific mechanisms are generally further classed according to whether they produce behavioral depression or stimulation. Those with specific mechanisms are classed by locus of action or specific therapeutic use. (From Gilman AG, et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p252)	Central Nervous System Drugs
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013329	Structure-Activity Relationship	The relationship between the chemical structure of a compound and its biological or pharmacological activity. Compounds are often classed together because they have structural characteristics in common including shape, size, stereochemical arrangement, and distribution of functional groups.
