Design, synthesis, structure-activity relationship, and in vivo activity of azabicyclic aryl amides as alpha7 nicotinic acetylcholine receptor agonists

A novel set of azabicyclic aryl amides have been identified as potent and selective agonists of the alpha7 nAChR. A two-pronged approach was taken to improve the potential hERG liability of previously disclosed alpha7 nAChR agonist, PNU-282,987, while maintaining the compound’s other desirable pharmacological properties. The first approach involved further exploration of the aryl carboxylic acid fragment of PNU-282,987, while the second approach focused on modification of the azabicyclic amine portion of PNU-282,987. The best compounds from each series are characterized by rapid brain penetration, good oral bioavailability in rat, and demonstrate in vivo efficacy in a rat P50 auditory sensory gating assay. At least one analog from each series (1h, 1o, 2a, 9a, and 18a) shows an improved hERG safety profile over PNU-282,987.

Amidino benzimidazole inhibitors of bacterial two-component systems

Amidino benzimidazoles have been identified as inhibitors of the bacterial KinA/Spo0F two-component system (TCS). Many of these inhibitors exhibit good in vitro antibacterial activity against a variety of susceptible and resistant Gram-positive organisms. The moiety at the 2-position of the benzimidazole was extensively modified. In addition, the regioisomeric benzoxazoles, heterocyclic replacements for the benzimidazole, have been synthesized and their activity against the TCS evaluated.

Prediction of cytochrome P450-mediated drug clearance in humans based on the measured activities of selected CYPs

Determining drug-metabolizing enzyme activities on an individual basis is an important component of personalized medicine, and cytochrome P450 enzymes (CYPs) play a principal role in hepatic drug metabolism. Herein, a simple method for predicting the major CYP-mediated drug clearance in vitro and in vivo is presented. Ten CYP-mediated drug metabolic activities in human liver microsomes (HLMs) from 105 normal liver samples were determined. The descriptive models for predicting the activities of these CYPs in HLMs were developed solely on the basis of the measured activities of a smaller number of more readily assayed CYPs. The descriptive models then were combined with the Conventional Bias Corrected in vitro-in vivo extrapolation method to extrapolate drug clearance in vivo. The Vmax, Km, and CLint of six CYPs (CYP2A6, 2C8, 2D6, 2E1, and 3A4/5) could be predicted by measuring the activities of four CYPs (CYP1A2, 2B6, 2C9, and 2C19) in HLMs. Based on the predicted CLint, the values of CYP2A6-, 2C8-, 2D6-, 2E1-, and 3A4/5-mediated drug clearance in vivo were extrapolated and found that the values for all five drugs were close to the observed clearance in vivo. The percentage of extrapolated values of clearance in vivo which fell within 2-fold of the observed clearance ranged from 75.2% to 98.1%. These findings suggest that measuring the activity of CYP1A2, 2B6, 2C9, and 2C19 allowed us to accurately predict CYP2A6-, 2C8-, 2D6-, 2E1-, and 3A4/5-mediated activities in vitro and in vivo and may possibly be helpful for the assessment of an individual’s drug metabolic profile.

Inhibition of aflatoxin B1 production by verbascoside and other olive polyphenols

In this study, the effects of pure olive phenolic compounds and olive mill wastewater (OMWW) (after membrane filtration treatments) on Aspergillus flavus growth and aflatoxin B1 (AFB1) production, were investigated. Five OMWWs coming from Greek (Lianolia, Koroneiki and Asprolia) and Italian (Cellina di Nardo and Coratina) olive oil cultivars, opportunely filtered using a membrane system, were added at two concentrations (5 and 15%) to growth medium, in order to evaluate their effect on A. flavus growth and AFB1 production. The OMWW fractions treatment, after 6 days of incubation, did not inhibit the fungal growth rate, but at 15% concentration significantly reduced the AFB1 production (ranging from 88 to 100%). A similar approach was used for caffeic acid, hydroxytyrosol, tyrosol and verbascoside, the major pure phenolic compounds identified in OMWW fractions. They were evaluated at increasing doses (10, 50 and 100 mug/ml) following both AFB1 production and fungal growth. At the highest concentration (100 mug/ml) all pure compounds showed a reduction of about 99% of AFB1 production without any influence on fungal growth. This is the first time in which OMWWs and their main phenolics were used in the treatments against AFB1 production. The results obtained could provide possible new strategies for preventing AFB1 food contamination using olive polyphenols and OMWW fractions with anti-aflatoxigenic effect, and permitting to harness in a sustainable way an olive oil by-product.

On water catalyst-free synthesis of benzo[: D] imidazo[2,1- b] thiazoles and novel N -alkylated 2-aminobenzo [d] oxazoles under microwave irradiation

A highly efficient unprecedented catalyst-free microwave-assisted procedure for synthesizing benzo[d]imidazo[2,1-b]thiazoles and N-alkylated 2-aminobenzo[d]oxazol in green media was developed. The transformation provided rapid access to functionalized benzo[d]imidazo[2,1-b]thiazoles from 2-aminobenzothiazole and N-alkylated 2-aminobenzo[d]oxazole from 2-aminobenzoxazole scaffolds under mild transition-metal-free conditions. This synthetic manipulation is expected to greatly expand the repertoire of reaction types in heterocyclic chemistry and pave the way for new syntheses of bioactive compounds.

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 4570-41-6 is helpful to your research. Related Products of 4570-41-6
