A series of five fluorescent ligands (L1–L5) for anions were designed and synthesized. Urea, thiourea, and cyanoguanidine moieties were chosen as the binding groups, while 3,5-bis(trifluoromethyl)phenyl, coumarin, and BODIPY were used as the chromophores. The cyanoguanidines L3–L5 were promptly synthesized from corresponding thioureas using EDCI followed by reaction with cyanamide in the presence of triethylamine. The absorption and emission properties of the ligands L1–L5 were studied in CH3CN; their coordination properties towards phosphate, pyrophosphate, and hydroxide anions, together with binding constants were evaluated.

A three series of thioureas, monothiourea type I (4a–g), 1,4-bisthiourea type II (5a–h) and 1,3-bisthiourea type III (6a–h) were synthesized. Their aromatase inhibitory activities have been evaluated. Interestingly, eight thiourea derivatives (4e, 5f–h, 6d, 6f–h) exhibited the aromatase inhibitory activities with IC50 range of 0.6–10.2 μM. The meta-bisthiourea bearing 4-NO2 group (6f) and 3,5-diCF3 groups (6h) were shown to be the most potent compounds with sub-micromolar IC50 values of 0.8 and 0.6 μM, respectively. Molecular docking also revealed that one of the thiourea moieties of these two compounds could mimic steroidal backbone of the natural androstenedione (ASD) via hydrophobic interactions with enzyme residues (Val370, Leu477, Thr310, and Phe221 for 6f, Val370, Leu477, Ser478, and Ile133 for 6h). This is the first time that the bisthioureas have been reported for their potential to be developed as aromatase inhibitors, in which the 4-NO2 and 3,5-diCF3 analogs have been highlighted as promising candidates.

An efficient and practical thiocarbonyl surrogate via combination of sulfur and chloroform has been developed. A variety of thiocarbamides and oxazolidinethiones have been established, including chiral thiourea catalysts and chiral oxazolidinethione auxiliaries with high selectivity. Meanwhile, pesticides Diafenthiuron (an acaricide), ANTU (a rodenticide), and Chloromethiuron (an insecticide) were practically synthesized through this method in gram scale. Dicholorocarbene, as the key intermediate, was further confirmed via a carbene-trapping control experiment.
