An article , which mentions 499-40-1, molecular formula is C12H22O11. The compound – (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal played an important role in people’s production and life.

The coordination chemistry of three bridging doubly-tridentate ligands, including the known compound 3,6-bis(di-2-pyridylmethyl)pyridazine (1), which is structurally similar to 1,4-bis(di-2-pyridylmethyl)phthalazine (2), and two pyrimidine-linked compounds 4,6-bis(di-2-pyridylmethyl)pyrimidine (3), and 4,6-bis(di-2-pyridylamino)pyrimidine (4), was investigated with FeII, NiII, and PdII metal salts. Ligands 3 and 4 were synthesized in one-pot reactions from easily obtained starting materials; compound 3 was synthesized from di-2-pyridylmethane and 4,6-diiodopyrimidine in 48% yield, while ligand 4 was prepared by reacting di-2-pyridylamine with 4,6-dichloropyrimidine in 27% yield. During the synthesis of 4, an additional compound, 4-chloro-6-(di-2-pyridylamino)pyrimidine (5), with only one tridentate binding site was obtained in 30% yield. Reactions of 1, 3, and 4 with Fe II or NiII salts gave two types of complexes, either discrete M2L or M2L2 assemblies. The Pd II complexes obtained were also characterized as discrete M 2L complexes. The compounds were characterized by a combination of NMR and IR spectroscopy, microanalysis and X-ray crystallography. Noticeable differences in the structures obtained for NiII coordination complexes with the carbon-linked (3) and nitrogen-linked (4) ligands were observed, whereby the nitrogen linker adopted a trigonal planar geometry and prevented tridentate facial coordination of the octahedral metal centres. The magnetic properties of dinuclear FeII complexes of 1 were examined to see if they showed spin-crossover effects, a feature recently observed by others in other dinuclear helicate complexes, but the complexes remained high-spin at all temperatures between 300 and 2 K.

In the current paper, we report the kinetics of bifunctional dinuclear platinum(ii) complexes viz., 1,2-N,N?-di-(2,2-dipyridylamine)ethanetetraaquaplatinum(ii), PtL2, 1,3-N,N?-di-(2,2-dipyridylamine)propanetetraaquaplatinum(ii), PtL3, 1,4-N,N?-di-(2,2-dipyridylamine)butanetetraaquaplatinum(ii), PtL4, 1,5-N,N?-di-(2,2-dipyridylamine)pentanetetraaquaplatinum(ii), PtL5 and 1,6-N,N?-di-(2,2-dipyridylamine)hexanetetraaquaplatinum(ii), PtL6. The substitution reactions were carried out on tetraaqua complexes with thiourea nucleophiles under pseudo-first-order conditions as a function of nucleophile concentration and temperature by stopped-flow and UV-vis spectrophotometric techniques. An experimental study was conducted with the aim of determining the influence of alkyl chains on the steric and electronic structure of dinuclear platinum(ii) complexes. The reactivity of these complexes was dependent on the length of the alkyl spacer. The results obtained herein demonstrate the intriguing odd-even effects induced by the alkyl chain on the complexes. Artificial constraints imposed by the alkyl chain significantly affect their conformational structure to be either synperiplanar (syn-) or antiperiplanar (anti-) characterized by the odd and even effect. The kinetic, mechanistic and conformational behaviour was influenced by the size of the alkyl chain in accordance with odd-even alterations of the spacer. Computational modeling using density functional theory (DFT) calculations supplemented experimental findings that structural features and the reactivity pattern of these organometallic complexes are governed by both steric and electronic effects arising from the flexibility and inductive nature of the alkyl spacer. The strong sigma-donicity of longer alkyl chains favours sufficient accumulation of electron density at the metal centre and stabilizes a 14-electron intermediate. The study shows the HOMO-LUMO energy (DeltaE) is affected by the length of the spacer. Kinetic and DFT data indicate electron donation by the alkyl spacer. The low positive values of enthalpy of activation and significantly large negative values of entropy of activation indicate an associative mechanism of substitution.

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 499-40-1 is helpful to your research., Reference of 499-40-1

The re-emergence of chikungunya virus (CHIKV) is a serious global health threat. CHIKV is an alphavirus that is transmitted to humans by Aedes mosquitoes; therefore, their wide distribution significantly contributes to the globalization of the disease. Unfortunately, no effective antiviral drugs are available. We have identified a series of 3-aryl-[1,2,3]triazolo[4,5-d]pyrimidin-7(6H)-ones as selective inhibitors of CHIKV replication. New series of compounds have now been synthesized with the aim to improve their physicochemical properties and to potentiate the inhibitory activity against different CHIKV strains. Among these newly synthesized compounds modified at position 3 of the aryl ring, tetrahydropyranyl and N-t-butylpiperidine carboxamide derivatives have shown to elicit potent antiviral activity against different clinically relevant CHIKV isolates with 50% effective concentration (EC50) values ranging from 0.30 to 4.5 muM in Vero cells, as well as anti-CHIKV activity in human skin fibroblasts (EC50 = 0.1 muM), a clinically relevant cell system for CHIKV infection.
