The article 《Discovery of a pyrazolo[1,5-a]pyrimidine derivative (MT-3014) as a highly selective PDE10A inhibitor via core structure transformation from the stilbene moiety》 in relation to this compound, is published in Bioorganic & Medicinal Chemistry. Let’s take a look at the latest research on this compound (cas:136725-55-8).

We have developed a new class of PDE10A inhibitor, a pyrazolo[1,5-a]pyrimidine derivative MT-3014 (1, I). A previous compound introduced was deprioritized due to concerns for E/Z-isomerization and glutathione-adduct formation at the core stilbene structure. We discovered pyrazolo [1,5-a] pyrimidine as a new lead scaffold by structure-based drug design utilizing a co-crystal structure with PDE10A. The lead compound was optimized for in vitro activity, solubility, and selectivity against human ether-a-́go-go related gene cardiac channel binding. We observed that I shows excellent efficacy in rat conditioned avoidance response test and suitable pharmacokinetic properties in rats, especially high brain penetration.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: (R)-(-)-3-Fluoropyrrolidine Hydrochloride, is researched, Molecular C4H9ClFN, CAS is 136725-55-8, about Urea Derivatives of 2-Aryl-benzothiazol-5-amines: A New Class of Potential Drugs for Human African Trypanosomiasis, the main research direction is aryl benzothiazolamine preparation trypanosomicide human African trypanosomiasis treatment.Related Products of 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.

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 Enantiomorphic Perovskite Ferroelectrics with Circularly Polarized Luminescence, published in 2020-03-11, which mentions a compound: 136725-55-8, Name is (R)-(-)-3-Fluoropyrrolidine Hydrochloride, Molecular C4H9ClFN, COA of Formula: C4H9ClFN.

Materials with circularly polarized luminescence (CPL) activity have immense potential applications in mol. switches, optical sensors, information storage, asym. photosynthesis, 3D optical displays, biol. probe, and spintronic devices. However, the achiral architectures of most of the luminophores severely limit their practical needs. Within this context, mol. ferroelecs. with striking chem. variability and structure-property flexibility bring light to the assembly of CPL-active ferroelec. materials. Herein, we report organic-inorganic perovskite enantiomorphic ferroelecs., (R)- and (S)-3-(fluoropyrrolidinium)MnBr3, undergoing a 222F2-type ferroelec. phase transition at 273 K. Their mirror relationships are verified by both single-crystal X-ray diffraction and vibrational CD (VCD). Furthermore, the corresponding Cotton effect for two chiral crystals was captured by mirror CPL activity. This may be assigned to the inducing interaction between the achiral luminescent perovskite framework and chiral organic components. As far as we know, this is the first mol. ferroelec. with CPL activity. Accordingly, this will inspire intriguing research in mol. ferroelecs. with CPL activity and holds great potential for the development of new optoelectronic devices.

The article 《Novel Human Neutral Sphingomyelinase 2 Inhibitors as Potential Therapeutics for Alzheimer’s Disease》 in relation to this compound, is published in Journal of Medicinal Chemistry. Let’s take a look at the latest research on this compound (cas:136725-55-8).

Neutral sphingomyelinase 2 (nSMase2) catalyzes the cleavage of sphingomyelin to phosphorylcholine and ceramide, an essential step in the formation and release of exosomes from cells that is critical for intracellular communication. Chronic increase of brain nSMase2 activity and related exosome release has been implicated in various pathol. processes, including the progression of Alzheimer’s disease (AD), making nSMase2 a viable therapeutic target. Recently, we identified phenyl(R)-(1-(3-(3,4-dimethoxyphenyl)-2,6-dimethylimidazo[1,2-b] pyridazin-8-yl) pyrrolidin-3-yl)-carbamate 1 (PDDC)(I), the first nSMase2 inhibitor which possesses both favorable pharmacodynamics and pharmacokinetic (PK) parameters, including substantial oral bioavailability, brain penetration and significant inhibition of exosome release from the brain in vivo. Herein we demonstrate efficacy of 1 (PDDC) in a mouse model of AD and detail extensive structure-activity relationship (SAR) studies with 70 analogs, unveiling several that exert similar or higher activity against nSMase2 with favorable pharmacokinetic properties.
