Kinetics of synthesis of bis-(benzoxazolyl-2-methyl) sulfide under phase-transfer catalysis conditions

Kinetics of synthesis of bis-(benzoxazolyl-2-methyl) sulfide (BBMS) is investigated under phase-transfer catalysis conditions. Thus, the reaction of 2-chloromethylbenzoxazole and sodium sulfide is carried out in a two-phase (organic/water) medium, and quaternary ammonium salt and quaternary phosphonium salt are used as phase-transfer catalyst (PTC) in the reaction. The conversion of 2-chloromethylbenzoxazole is dramatically enhanced by adding a small quantity of PTC and is also greatly affected by the reaction conditions. The effects of various reaction variables on the kinetics are investigated, including the amount of catalyst, the temperature, the kinds of catalysts, the kinds of solvents, and the agitation speed. An interfacial reaction mechanism is proposed to explain the characteristics of the reaction. A pseudo-firstorder rate model is established to describe the relationship between the fractional conversion and the reaction time. The kinetics data demonstrate that the model is suitable to the reaction of synthesis of BBMS.

Development of a Series of Kynurenine 3-Monooxygenase Inhibitors Leading to a Clinical Candidate for the Treatment of Acute Pancreatitis

Recently, we reported a novel role for KMO in the pathogenesis of acute pancreatitis (AP). A number of inhibitors of kynurenine 3-monooxygenase (KMO) have previously been described as potential treatments for neurodegenerative conditions and particularly for Huntington?s disease. However, the inhibitors reported to date have insufficient aqueous solubility relative to their cellular potency to be compatible with the intravenous (iv) dosing route required in AP. We have identified and optimized a novel series of high affinity KMO inhibitors with favorable physicochemical properties. The leading example is exquisitely selective, has low clearance in two species, prevents lung and kidney damage in a rat model of acute pancreatitis, and is progressing into preclinical development.

One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Recommanded Product: 6-Bromo-5-chlorobenzo[d]oxazol-2(3H)-one, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 5579-85-1

Determination of brain cytochrome P450 2E1 activity in rat with the probe of chlorzoxazone by liquid chromatography-mass spectrometry

A simple and sensitive method was developed for the determination of cytochrome P450 2E1 (CYP2E1) activity based on the liquid chromatography-mass spectrometry (LC-MS) analysis of 6-hydroxychlorzoxazone generated by 6-hydroxylation of chlorzoxazone under specific catalysis of CYP2E1. In the proposed method, 2-benzoxazolinone was chosen as internal standard and isopropyl ether was used as extraction solvent for sample preparation. The inter-day and intra-day precisions at low, medium and high concentrations of 6-hydroxychlorzoxazone were below 20.0%, and the LOD (S/N = 3) was 0.05. ng/mL. This method was applied to analyze the CYP2E1 activity of rat in different brain regions including frontal cortex (FC), cerebellum (CB), brain stem (BS), hippocampus (HC), striatum (ST), thalamus (TH), and olfactory bulb (OB). The results confirmed that chlorzoxazone was a suitable probe for the determination of CYP2E1 activity in brain regions and samples with low content of CYP2E1.

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 1750-45-4 is helpful to your research. Electric Literature of 1750-45-4

Metabolic drug-drug interaction potential of macrolactin a and 7-O-succinyl macrolactin a assessed by evaluating cytochrome P450 inhibition and induction and UDP-glucuronosyltransferase inhibition in Vitro

Macrolactin A (MA) and 7-O-succinyl macrolactin A (SMA), polyene macrolides containing a 24-membered lactone ring, show antibiotic effects superior to those of teicoplanin against vancomycin-resistant enterococci and methicillin-resistant Staphylococcus aureus. MA and SMA are currently being evaluated as antitumor agents in preclinical studies in Korea. We evaluated the potential of MA and SMA for the inhibition or induction of human liver cytochrome P450 (CYP) enzymes and UDP-glucuronosyltransferases (UGTs) in vitro to assess their safety as new molecular entities. We demonstrated that MA and SMA are potent competitive inhibitors of CYP2C9, with Ki values of 4.06 muM and 10.6 muM, respectively. MA and SMA also weakly inhibited UGT1A1 activity, with Ki values of 40.1 muM and 65.3 muM, respectively. However, these macrolactins showed no time-dependent inactivation of the nine CYPs studied. In addition, MA and SMA did not induce CYP1A2, CYP2B6, or CYP3A4/5. On the basis of an in vitro-in vivo extrapolation, our data strongly suggested that MA and SMA are unlikely to cause clinically significant drugdrug interactions mediated via inhibition or induction of most of the CYPs involved in drug metabolism in vivo, except for the inhibition of CYP2C9 by MA. Similarly, MA and SMA are unlikely to inhibit the activity of UGT1A1, UGT1A4, UGT1A6, UGT1A9, and UGT2B7 enzymes in vivo. Although further investigations will be required to clarify the in vivo interactions of MA with CYP2C9-targeted drugs, our findings offer a clearer understanding and prediction of drug-drug interactions for the safe use of MA and SMA in clinical practice.

Dearomatizing radical cyclizations and cyclization cascades triggered by electron-transfer reduction of amide-type carbonyls

Highly selective dearomatizing radical cyclizations and cyclization cascades, triggered by single electron transfer to amide-type carbonyls by SmI2-H2O-LiBr, provide efficient access to unprecedented spirocyclic scaffolds containing up to five stereocenters with high diastereocontrol. The first dearomatizing radical cyclizations involving radicals derived from amide carbonyls by single electron transfer take place under mild conditions and engage a range of aromatic and heteroaromatic systems present in the barbiturate substrates. The radical cyclizations deliver new polycyclic hemiaminals or enamines selectively, depending on the conditions employed, that are based on a medicinally proven scaffold and can be readily manipulated.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 41014-43-1, you can also check out more blogs about41014-43-1

New antimitotic agents with activity in multi-drug-resistant cell lines and in vivo efficacy in murine tumor models

During a screen for compounds that could inhibit cell proliferation, a series of new tubulin-binding compounds was identified with the discovery of oxadiazoline 1 (A-105972). This compound showed good cytotoxic activity against non-multi-drug-resistant and multi-drug-resistant cancer cell lines, but its utility in vivo was limited by a short half-life. Medicinal chemistry efforts led to the discovery of indolyloxazoline 22g (A-259745), which maintained all of the in vitro activity seen with oxadiazoline 1, but also demonstrated a better pharmacokinetic profile, and dose-dependent in vivo activity. Over a 28 day study, indolyloxazoline 22g increased the life span of tumor-implanted mice by up to a factor of 3 upon oral dosing. This compound, and others of its structural class, may prove to be useful in the development of new chemotherapeutic agents to treat human cancers.

The tyrosine kinase inhibitor nilotinib selectively inhibits cyp2c8 activities in human liver microsomes

The tyrosine kinase inhibitor nilotinib was examined for its inhibition of cytochrome P450s (CYPs) in human liver microsomes and in human CYPs expressed in a baculovirus-insect cell system. Nilotinib demonstrated preferential inhibition of CYP2C8-mediated paclitaxel 6alpha-hydroxylation, rosiglitazone hydroxylation and amodiaquine N-deethylation in human liver microsomes, with IC50 values of 0.4, 7.5 and 0.7 muM, respectively. The IC 50 value of nilotinib for paclitaxel 6alpha-hydroxylation was 20-fold lower than that of the other five tyrosine-kinase inhibitors tested. Nilotinib appears to display competitive inhibition against paclitaxel 6alpha-hydroxylation and amodiaquine N-deethylation, with estimated mean Ki values of 0.90 and 0.15 muM in human liver microsomes and 0.10 and 0.61 muM in recombinant human CYP2C8, respectively. These results are consistent with those of molecular docking simulations, where paclitaxel could not access the CYP2C8 catalytic site in the presence of nilotinib, but the binding of midazolam, a substrate of CYP3A4, to the catalytic site of CYP3A4 was not affected by nilotinib. The demonstrated inhibitory activity of nilotinib against CYP2C8 at concentrations less than those observed in patients who received nilotinib therapy is of potential clinical relevance and further in vivo exploration is warranted.
