Cytisine very potently binds and activates the alpha3beta4 and alpha7 nicotinic subtypes, but only partially agonises the alpha4beta2 subtype. Although with a lower affinity than cytisine, new cytisine derivatives with different substituents on the basic nitrogen (CC1-CC8) bind to both the heteromeric and homomeric subtypes, with higher affinity for brain [3H]epibatidine receptors. The cytisine derivatives were tested on the Ca2+ flux of native or transfected cell lines expressing the rat alpha7, or human alpha3beta4 or alpha4beta2 subtypes using Ca2+ dynamics in conjunction with a fluorescent image plate reader. None elicited any response at doses of up to 30-100 muM, but all inhibited agonist-induced responses. Compounds CC5 and CC7 were also electrophysiologically tested on oocyte-expressed rat alpha4beta2, alpha3beta4 and alpha7 subtypes. CC5 competitively antagonised the alpha4beta2 and alpha3beta4 subtypes with similar potency, whereas CC7 only partially agonised them with maximum responses of respectively 3% and 11% of those of 1 mM acetylcholine. Neither compound induced any current in the oocyte-expressed alpha7 subtype, and both weakly inhibited acetylcholine-induced currents. Adding chemical groups of a different class or size to the basic nitrogen of cytisine leads to compounds that lose full agonist activity on the alpha3beta4 and alpha7 subtypes.

Synthetic Route of 5469-70-5, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 5469-70-5, molcular formula is C4H5N3, introducing its new discovery.

In this work, a series of 2-substituted-thio-N-(4-substituted-thiazol/1H-imidazol-2-yl)acetamide derivatives were developed as beta-secretase (BACE-1) inhibitors. Supported by docking study, a small library of derivatives were designed, synthesized and biologically evaluated in vitro. In addition, the selected compounds were tested with affinity (KD) towards BACE-1, blood brain barrier (BBB) permeability and cytotoxicity. The studies revealed that the most potent analog 41 (IC50 = 4.6 muM) with high predicted BBB permeability and low cellular cytotoxicity, could serve as a good lead structure for further optimization.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 5469-70-5 is helpful to your research. Synthetic Route of 5469-70-5

New classes of CRTH2 antagonists, the pyridazine linker containing indole acetic acids, are described. The initial hit 1 had good potency but poor permeability, metabolic stability, and PK. Initial optimization led to compounds of type 2 with low oxidative metabolism but poor oral bioavailability. Poor permeability was identified as a liability for these compounds. Addition of a linker between the indole and diazine moieties afforded a series with good potency, low rates of metabolism, moderate permeability, and good oral bioavailability in rodents. 32 was identified as the development track candidate. It was potent in cell based, binding, and whole blood assays and exhibited good PK profile. It was efficacious in mouse models of contact hypersensitivity (1 mg/kg b.i.d.) and house dust (20 mg/kg q.d.) when dosed orally. In sheep asthma, administration at 1 mg/kg iv completely blocked the LAR and AHR and attenuated the EAR phase.

A kinetic study has been made of the first-order thermal decomposition of the title compounds into ethylene and the corresponding aza-substituted pyridines, between 650 and 713 K.The relative elimination rates at 650 K are (2-ethoxypyridine = 1): 0.545, 10.0, 1.03, 1.12, 9.68, and 3.28, respectively.The electronic effects of the aza ‘substituent’ are small, and a more important factor appears to be the C-N ?-bond order; this latter accounts for the high reactivity of the pyridazines.The effects of the chloro substituent and of the aza ‘substituent’ are explicable in terms of a balance between electron withdrawal from the C-O bond (producing deactivation) and from the nitrogen involved in the cyclic transition state (producing deactivation).The effects of the chloro substituents confirm that the most important step of the reaction is breaking of the C-O bond.The statistically corrected rate (per ring nitrogen) of 2-ethoxypyrimidine is unexpectedly low.This may reflect difficulty in achieving the coplanar transition state in which the lone pairs in the s-orbitals of oxygen and the nitrogen not involved in the elimination are brought into close proximity.
