Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 5451-40-1, is researched, SMILESS is C2=NC1=C(C(=NC(=N1)Cl)Cl)[NH]2, Molecular C5H2Cl2N4Journal, Article, Research Support, Non-U.S. Gov’t, Bioorganic Chemistry called 6-Substituted purines as ROCK inhibitors with anti-metastatic activity, Author is Voller, Jiri; Zahajska, Lenka; Plihalova, Lucie; Jerabkova, Jana; Burget, David; Pataki, Andreea Csilla; Krystof, Vladimir; Zatloukal, Marek; Brabek, Jan; Rosel, Daniel; Mik, Vaclav; Tkac, Martin; Pospisil, Tomas; Gucky, Tomas; Dolezal, Karel; Strnad, Miroslav, the main research direction is melanoma antitumor antimetastasis purine ROCK2; Anti-metastatic activity; Melanoma; Protein kinase inhibitor; ROCK.Safety of 2,6-Dichloropurine.

Rho-associated serine/threonine kinases (ROCKs) are principal regulators of the actin cytoskeleton that regulate the contractility, shape, motility, and invasion of cells. We explored the relationships between structure and anti-ROCK2 activity in a group of purine derivatives substituted at the C6 atom by piperidin-1-yl or azepan-1-yl groups. Structure-activity relationship (SAR) analyses suggested that anti-ROCK activity is retained, and may be further increased, by substitution of the parent compounds at the C2 atom or by expansion of the C6 side chain. These inhibitors of ROCK can reach effective concentrations within cells, as demonstrated by a decrease in phosphorylation of the ROCK target MLC, and by inhibition of the ROCK-dependent invasion of melanoma cells in the collagen matrix. Our study may be useful for further optimization of C6-substituted purine inhibitors of ROCKs and of other sensitive kinases identified by the screening of a broad panel of protein kinases.

From this literature《6-Substituted purines as ROCK inhibitors with anti-metastatic activity》,we know some information about this compound(5451-40-1)Safety of 2,6-Dichloropurine, but this is not all information, there are many literatures related to this compound(5451-40-1).

Related Products of 1194-22-5. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 6-Hydroxy-2-methylpyrimidin-4(3H)-one, is researched, Molecular C5H6N2O2, CAS is 1194-22-5, about Novel dinitromethyl-featured polynitro energetic salts. Author is Li, Ying; Huang, Haifeng; Lin, Xiangyang; Pan, Renming; Yang, Jun.

A unique and facile method was developed to synthesize a new class of energetic salts based on 2-amino-1,1,5,5-tetranitro-4-oxo-3-aza-pentene. All the salts were fully characterized by NMR (1H and 13C), IR spectroscopy and elemental anal. Furthermore, the crystal structure of the guanidinium salt was determined by single-crystal X-ray diffraction. The differential scanning calorimetry (DSC) results showed that the decomposition temperatures of these salts were between 126.2 °C and 148.8 °C. The densities of these salts lie in the range of 1.745 to 1.880 g cm-3. Their impact sensitivities and friction sensitivities were measured to be in the range of 1-16 J and 48-84 N, resp. All the salts exhibited promising detonation performances (detonation pressure: 28.6 to 34.3 GPa; detonation velocity: 8037 to 8674 m s-1), and the detonation performances of one of the salts were comparable to those of RDX.

The multicomponent reaction of aldehydes, benzoylisothiocyanate and alkyl bromides in the presence of ammonium acetate, sodium cyanide and a catalytic amount of KF/Clinoptilolite nanoparticles (KF/CP NPs) in the water at 100°C was investigated. In these reactions, thiazole I [R= H, Me, i-Pr; R1 = ethoxycarbonyl, 4-methoxyphenyl, 4-bromophenyl] were produced in good to excellent yields and short time. Also, the antioxidant activity was studied for some newly synthesized compounds using the DPPH radical trapping and reducing of ferric ion experiments and compared the results with synthetic antioxidants (TBHQ and BHT). As a result, the compounds I [R= i-Pr; R1 = ethoxycarbonyl] showed excellent DPPH radical trapping and reducing the strength of ferric ion. These compounds I [R= H, Me, i-Pr; R1 = ethoxycarbonyl, 4-methoxyphenyl, 4-bromophenyl] have biol. potential because of the thiazole core. For this reason, the antimicrobial activity of some synthesized compounds I [R= H, Me, i-Pr; R1 = ethoxycarbonyl, 4-methoxyphenyl, 4-bromophenyl] was studied by employing the disk diffusion test on Gram-pos. bacteria and Gram-neg. bacteria. The results of the disk diffusion test showed that these compounds I [R= H, Me, i-Pr; R1 = ethoxycarbonyl, 4-methoxyphenyl, 4-bromophenyl] prevented bacterial growth.

Epilepsy is a chronic disorder that causes unprovoked, recurrent seizures like a sudden rush of elec. activity in the brain. Neuronal hyperexcitability in epilepsy is due to an imbalance between glutamate-mediated excitation and GABA-mediated inhibition. This prompted us to design newer CSF1R inhibitors as efficient therapeutic drugs for the treatment of epilepsy. Based on the common pharmacophoric features for the inhibition of CSF1R inhibitors, a series of leads were designed using computational methods. A virtual library consisting of newly designed 60 mols. as CSF1R inhibitors were constructed .Based on these facts, a virtual library has been generated with 60 newly designed ligands containing imidazole, benzo pyrrole, quinoline, oaxzole, quinoxaline, benzimidazole, heterocyclic nucleus as CSF1R inhibitors (60). The binding mechanism of newly designed ligands with target enzymes CSF1R inhibitors was studied using Auto dock tools 1.5.6. The designed compounds were subjected and filtered by applying ADMET properties. In comparison with docking scores of standard antiepileptic drugs vigabatrin (GABA-2.14, CSF1R-1, 31) and sodium valproate (GABA-3.19, CSF1R-3.6) and the newly designed ligands, CS1 (-6.61), CS3 (-6.22), CS14 (-6.04) were found to be highly active hits than that of standards
