A series of N-alkyl substituted urea derivatives were synthesized and evaluated for their in vitro antibacterial and antifungal activities. The N-alkyl substituted urea derivatives bearing morpholine moiety (3a–3k) showed better activities than those bearing diethylamine moiety (2a–2f). Compounds having fluoro substituent at ortho (3c) and para (3b) positions of the phenyl ring exhibited potent antimicrobial

The present invention relates to novel compounds having histone deacetylase 6 (HDAC6) in-hibitory activity, stereoisomers thereof or pharmaceutically acceptable salts thereof the use thereof for the preparation of therapeutic medicaments, pharmaceutical compositions containing the same, a method for treating diseases using the composition, and methods for preparing the novel compounds. The novel compounds stereoisomers thereof or pharmaceutically acceptable salts thereof according to the present invention have histone deacetylase (HDAC) inhibitory activity and are effective for the prevention or treatment of HDAC6-mediated diseases, including infectious diseases; neoplasms; endocrine, nutritional and metabolic diseases; mental and be-havioral disorders; neurological diseases; diseases of the eye and adnexa; cardiovascular diseases; respiratory diseases; digestive diseases; diseases of the skin and subcutaneous tissue; diseases of the musculoskeletal system and connective tissue; or congenital malformations, deformations and chromosomal abnormalities.
A novel photocatalytic urea synthesis strategy is proposed for the preparation of ureas from amines and carbon disulfide (CS), with Rhodamine B utilized as the photocatalyst. Conducted under mild reaction conditions, this method does not require the use of extra oxidants and efficiently yields a series of (un)symmetrical ureas and benzimidazolones under blue light irradiation. Furthermore, control
提出了一种新的光催化尿素合成策略,以罗丹明 B 作为光催化剂,由胺和二硫化碳 (CS) 制备尿素。该方法在温和的反应条件下进行,不需要使用额外的氧化剂,并且在蓝光照射下有效地产生一系列(不)对称的脲和苯并咪唑酮。此外,还进行了氧18标记对照实验,结果表明尿素产品中的羰基氧主要来自空气中的氧,通过氧化脱硫过程获得。
