One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, HPLC of Formula: C4H3ClN2, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1120-95-2, Name is 3-Chloropyridazine, molecular formula is C4H3ClN2

Synthesis, radiolabeling and in vivo evaluation of [11C](R)-1- [4-[2-(4-methoxyphenyl)phenyl]piperazin-1-yl]-3-(2-pyrazinyloxy)-2-propanol, a potential PET radioligand for the 5-HT7receptor

In the search for a novel serotonin 7 (5-HT7) receptor PET radioligand we synthesized and evaluated a new series of biphenylpiperazine derivatives in vitro. Among the studied compounds, (R)-1-[4-[2-(4-methoxyphenyl) phenyl]piperazin-1-yl]-3-(2-pyrazinyloxy)-2-propanol ((R)-16), showed the best combination of affinity, selectivity, and lipophilicity, and was thus chosen for carbon-11 labelling and evaluation in pigs. After intravenous injection, [11C](R)-16 entered the pig brain and displayed reversible tracer kinetics. Pretreatment with the 5-HT7receptor selective antagonist SB-269970 (1) resulted in limited decrease in the binding of [11C](R)-16, suggesting that this radioligand is not optimal for imaging the brain 5-HT7receptor in vivo but it may serve as a lead compound for the design of novel 5-HT7receptor PET radioligands.

Discovery of 1-amino-5 H-pyrido[4,3-b]indol-4-carboxamide inhibitors of janus kinase 2 (JAK2) for the treatment of myeloproliferative disorders

The JAK-STAT pathway mediates signaling by cytokines, which control survival, proliferation, and differentiation of a variety of cells. In recent years, a single point mutation (V617F) in the tyrosine kinase JAK2 was found to be present with a high incidence in myeloproliferative disorders (MPDs). This mutation led to hyperactivation of JAK2, cytokine-independent signaling, and subsequent activation of downstream signaling networks. The genetic, biological, and physiological evidence suggests that JAK2 inhibitors could be effective in treating MPDs. De novo design efforts of new scaffolds identified 1-amino-5H-pyrido[4,3-b]indol-4-carboxamides as a new viable lead series. Subsequent optimization of cell potency, metabolic stability, and off-target activities of the leads led to the discovery of 7-(2-aminopyrimidin-5-yl)-1- {[(1R)-1-cyclopropyl-2,2,2-trifluoroethyl]amino}-5H-pyrido[4,3-b] indole-4-carboxamide (65). Compound 65 is a potent, orally active inhibitor of JAK2 with excellent selectivity, PK profile, and in vivo efficacy in animal models.

Photoreactions in crystals of sterically hindered dimethylenecyclopentanones 1 and trimethylenecyclopentanes 4 lead to E/Z isomerizations and 1,5-H shifts.The stereochemical result of the photodimerization in the crystalline state of the heterostilbenes 6 is apparently determined by the polarity (dipole moment), which governs the crystal packing as well.A strong dissymmetry of charge (as in 6a-g) gives rise to H(ead)/T(ail)-syn dimers 7.This correlates well with the molecular stacking in the crystals of 6c, as determined by X-ray analysis.A low dissymmetry of charge (as in 6h) leaves the crystals photostable.At medium polarity two products with H/T-syn and H/H-syn stereochemistry (7 and 8) or, in particular cases, only dimers of type 8 are formed.The precise stereochemistry is proved by comparison with the analyzed 1H-NMR parameters of esters of truxillic and truxinic acids.Bifunctional heterostilbenes like 12c are photostable in the crystalline state.However, strongly polar methoxycarbonyl (13) and acetyl groups (17, 21) lead to photoreactive crystals again.In the case of 17 this is also shown by X-ray analysis.Due to well-defined possibilities of movement, there are three products formed in terms of multiproduct topochemistry. 13 and 21 also form several products upon photoreaction in the crystal.

Synthesis and SAR of a new series of COX-2-selective inhibitors: Pyrazolo[1,5-alpha]pyrimidines

The synthesis and pharmacological activity of a series of bicyclic pyrazolo[1,5-alpha]pyrimidines as potent and selective cyclooxygenase-2 (COX-2) inhibitors are described. The new compounds were evaluated both in vitro (COX-1 and COX-2 inhibition in human whole blood) and in vivo (carrageenan-induced paw edema and air-pouch model). Modification of the pyrimidine substituents showed that 6,7-disubstitution provided the best activity and led to the identification of 3-(4-fluorophenyl)-6,7-dimethyl-2-(4-methylsulfonylphenyl) pyrazolo[1,5-alpha]pyrimidine (10f) as one of the most potent and selective COX-2 inhibitor in this series.
