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.

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

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.

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.

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.

A metal-free oxidative amination of benzoxazoles with primary amines and ammonia

An efficient synthesis of 2-aminobenzoxazoles is described by a direct oxidative amination of unfunctionalized benzoxazoles with primary amines. The reaction could be performed in the absence of transition metals by using catalytic amounts of a quaternary ammonium iodide and tert-butylhydroperoxide as a cheap and easy-to-handle co-oxidant. In addition to primary amines, aqueous solutions of NH3 were used to introduce a primary amine group into the heterocyclic core. Georg Thieme Verlag Stuttgart. New York.
