On December 31, 1998, Kawanishi, Hiroyuki; Morimoto, Hiroshi; Nakano, Takao; Watanabe, Tatsuya; Oda, Kuniyuki; Tsujihara, Kenji published an article.Category: chlorides-buliding-blocks The title of the article was Stereoselective synthesis of antifungal sulfoximines, novel triazoles II. And the article contained the following:

Novel triazole derivatives I (R = H, MeCO, MeNHCO, Me, MeO2CCH2) with an N-substituted sulfoximine moiety were synthesized and evaluated for antifungal activity. These compounds showed significantly weaker activity than I (R = H); the N-H moiety of the sulfoximine was extremely important for the activity. A practical and effective stereoselective synthesis of (-)-I (R = H), considered to be the most promising antifungal compound, has been developed. (-)-I (R = H) is prepared in seven steps, including two resolution steps, from the methylthiodifluoropropiophenone II, by epoxidation with Me3SO+ Cl-, diastereoselective sulfimine formation with chloramine T, addition of 1,2,4-triazole to the epoxide, oxidation of the sulfimine, acid hydrolysis of toluenesulfonyl group of the sulfoximine, and resolution with the novel resolving agent 1-(2,3,4-trichlorophenyl)ethanesulfonic acid [(+)-TCPES] III. The experimental process involved the reaction of trimethyloxosulphonium chloride(cas: 5034-06-0).Category: chlorides-buliding-blocks

On October 31, 1991, Shepard, Kenneth L.; Graham, Samuel L.; Hudcosky, Ronald J.; Michelson, Stuart R.; Scholz, Thomas H.; Schwam, Harvey; Smith, Anthony M.; Sondey, John M.; Strohmaier, Kim M. published an article.Reference of 4-Chloro-2-fluorotoluene The title of the article was Topically active carbonic anhydrase inhibitors. 4. [(Hydroxyalkyl)sulfonyl]benzene and [(hydroxyalkyl)sulfonyl]thiophenesulfonamides. And the article contained the following:

For several decades a goal for the treatment of primary open-angle glaucoma has been the development of a topically active carbonic anhydrase inhibitor. (Hydroxyalkyl)sulfonyl-substituted benzene- and thiophenesulfonamides I [R = (CH2)nOH, CH2CH(OH)CH2OH, CH2CH2CMe2OH, etc., n = 2-5; R1 = H, Cl, F, NO2, CO2H, CO2Me, NH2; X = S, SO2] and II [R2 = (CH2)nOH, (CH2)mCO2Me, (CH2)3O2CCH2OMe, (CH2)3O2CCH2CHMe2, (CH2)3NHCH2CHMe2, X = S, SO2, n = 2-4, m = 2, 3] were prepared and examined for carbonic anhydrase inhibitory activity. Thus, condensation of 2-mercaptoethanol with (bromophenylsulfonyl)formamidine III gave I [R = (CH2)2OH, R1 = H, X = S]. These compounds exhibit inhibition of carbonic anhydrase II in the nanomolar range and lower intraocular pressure in the α-chymotrypsinized rabbit model of ocular hypertension after topical instillation. The inhibitory potency could be increased by converting a sulfide to the sulfone. Adding an extra methylene into the 4-substituent of benzene derivatives increases the inhibitory potency slightly more than oxidation of the sulfide. The experimental process involved the reaction of 4-Chloro-2-fluorotoluene(cas: 452-75-5).Reference of 4-Chloro-2-fluorotoluene

On December 16, 2020, Wang, Peng-Fei; Jensen, Anders A.; Bunch, Lennart published an article.Related Products of 89-77-0 The title of the article was From Methaqualone and Beyond: Structure-Activity Relationship of 6-, 7-, and 8-Substituted 2,3-Diphenyl-quinazolin-4(3H)-ones and in Silico Prediction of Putative Binding Modes of Quinazolin-4(3H)-ones as Positive Allosteric Modulators of GABAA Receptors. And the article contained the following:

Methaqualone (2-methyl-3-(o-tolyl)-quinazolin-4(3H)-one, MTQ) is a moderately potent pos. allosteric modulator (PAM) of GABAA receptors (GABAARs). In a previous structure-activity relationship (SAR) study probing the importance of 2- and 3-substituents in the quinazolin-4(3H)-one scaffold, several potent GABAAR PAMs were identified, including 2,3-diphenylquinazolin-4(3H)-one (PPQ) and 3-(2-chlorophenyl)-2-phenylquinazolin-4(3H)-one (Cl-PPQ). Here, PPQ was applied as lead in a SAR study of 6-, 7-, and 8-substituents in the quinazolin-4(3H)-one by synthesis and functional characterization of 36 PPQ analogs at various GABAAR subtypes. While none of the new analogs were significantly more potent than PPQ or displayed pronounced subtype selectivity across the GABAARs tested, several interesting SAR observations were extracted from the study. In an in silico study, the putative binding modes of MTQ, PPQ, and Cl-PPQ in the transmembrane β2(+)/α1(-) interface of the α1β2γ2S GABAAR were predicted. Several plausible binding modes were identified for the three PAMs, and rationalization of the mol. basis for their different modulatory potencies was attempted. The experimental process involved the reaction of 2-Amino-4-chlorobenzoic acid(cas: 89-77-0).Related Products of 89-77-0
