Keywords: ethylurea pyrazole derivative preparation Trypanosoma brucei cruzi Chagas. We’ll tell you more about this compound (cas:136725-55-8).

Trypanosoma brucei (T. brucei) and Trypanosoma cruzi (T. cruzi) are causative agents of parasitic diseases known as human African trypanosomiasis and Chagas disease, resp. Together, these diseases affect 68 million people around the world. Current treatments are unsatisfactory, frequently associated with intolerable side-effects, and generally inadequate in treating all stages of disease. In this paper, we report the discovery of N-ethylurea pyrazoles that potently and selectively inhibit the viability of T. brucei and T. cruzi. Sharp and logical SAR led to the identification of 54 as the best compound, with an in vitro IC50 of 9 nM and 16 nM against T. b. brucei and T. cruzi, resp. Compound 54 demonstrates favorable physicochem. properties and was efficacious in a murine model of Chagas disease, leading to undetectable parasitemia within 6 days when CYP metabolism was inhibited.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Discovery of Potent N-Ethylurea Pyrazole Derivatives as Dual Inhibitors of Trypanosoma brucei and Trypanosoma cruzi, published in 2020-03-12, which mentions a compound: 136725-55-8, Name is (R)-(-)-3-Fluoropyrrolidine Hydrochloride, Molecular C4H9ClFN, Formula: C4H9ClFN.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Facile and efficient syntheses of novel (S)- and (R)-3-fluoropyrrolidines and 3,3-difluoropyrrolidine, published in 1995-01-31, which mentions a compound: 136725-55-8, mainly applied to fluoropyrrolidine enantiomeric synthesis; difluoropyrrolidine enantiomeric; pyrrolidine fluoro difluoro, Synthetic Route of C4H9ClFN.

Novel enantiomeric 3-fluoropyrrolidines and 3,3-difluoropyrrolidine were obtained in high yield starting from the enantiomerically pure and com. available (2S,4R)-4-hydroxyproline. Spray-dried potassium fluoride and diethylaminosulfur trifluoride were used to introduce one or two fluorine atoms, resp.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (R)-(-)-3-Fluoropyrrolidine Hydrochloride( cas:136725-55-8 ) is researched.SDS of cas: 136725-55-8.Patrick, Donald A.; Gillespie, J. Robert; McQueen, Joshua; Hulverson, Matthew A.; Ranade, Ranae M.; Creason, Sharon A.; Herbst, Zackary M.; Gelb, Michael H.; Buckner, Frederick S.; Tidwell, Richard R. published the article 《Urea Derivatives of 2-Aryl-benzothiazol-5-amines: A New Class of Potential Drugs for Human African Trypanosomiasis》 about this compound( cas:136725-55-8 ) in Journal of Medicinal Chemistry. Keywords: aryl benzothiazolamine preparation trypanosomicide human African trypanosomiasis treatment. Let’s learn more about this compound (cas:136725-55-8).

A previous publication from this lab explored the antitrypanosomal activities of novel derivatives of 2-(2-benzamido)ethyl-4-phenylthiazole, which had been identified as a hit against Trypanosoma brucei, the causative agent of human African trypanosomiasis. While a number of these compounds, particularly the urea analogs, were quite potent, these mols. as a whole exhibited poor metabolic stability. The present work describes the synthesis of 65 new analogs arising from medicinal chem. optimization at different sites on the mol. The most promising compounds were the urea derivatives of 2-aryl-benzothiazol-5-amines. One such analog, (S)-2-(3,4-difluorophenyl)-5-(3-fluoro-N-pyrrolidylamido)benzothiazole (I) was chosen for in vivo efficacy studies based upon in vitro activity, metabolic stability, and brain penetration. This compound attained 5/5 cures in murine models of both early and late stage human African trypanosomiasis, representing a new lead for the development of drugs to combat this neglected disease.

Amides derived from fluorinated pyrrolidines and 4-substituted cyclohexylglycine analogs have been prepared and evaluated as inhibitors of dipeptidyl dipeptidase IV (DP-IV). Analogs which incorporated (S)-3-fluoropyrrolidine showed good selectivity for DP-IV over quiescent cell proline dipeptidase (QPP). Amide I had good pharmacokinetic properties and was orally active in an oral glucose tolerance test in lean mice.

Comparative X-ray structure studies reveal that C-F bond incorporation into the peripheral pyrrolidine moieties of the G-quadruplex DNA binding ligand BSU6039 leads to a distinct pyrrolidine ring conformation, relative to the non-fluorinated analog, and with a different binding mode involving reversal of the pyrrolidinium N+-H orientation.
