Removal of the ethoxycarbonyl group in ethyl cyano-(2,2-dimethyl-4-propyltetrahydro-2H-pyran-4 -yl)acetate afforded the corresponding (2,2-dimethyl-4-propyltetrahydro-2H-pyran-4-yl)acetonitrile. The reduction of the latter with lithium aluminum hydride furnished 2-(2,2-dimethyl-4-propyltetrahydro-2H-pyran- 4-yl)ethanamine, which reacted with furfural and a heterocyclic ketone followed by reduction to form the secondary amines and some amides. Hydrolysis of the above nitrile resulted in the corresponding acid, which was converted in a series of amides.

The CB2 receptor is an attractive target for the treatment of a wide range of diseases and pathological conditions. Compounds that selectively activate the CB2 receptor are desirable as this avoids CB1-mediated psychoactive effects. Heteroarylidene-benzamides have demonstrated efficacy as selective CB2 receptor agonists. We aimed to expand the structure-activity relationship studies of this series of compounds by investigating the heteroaromatic core via the synthesis and in vitro evaluation of a small library of various heteroaromatic benzamide analogues. As heteroaromatic amides are privileged scaffolds in drug design, methods to synthesise them are of interest. Concise and reliable synthetic strategies were developed to access these novel analogues. The ?ylidene-benzamide moiety is shown to be essential for CB activity as all amide derivatives exhibit no functional activity at either CB2 or CB1 receptors.

High Pressure Carbon Dioxide (HPCD) treatment was applied to the pasteurization of coconut water in order to guarantee both its microbial stability and preserve its nutritional and sensory attributes. It was demonstrated that 120 bar, 40 C, 30 min were the optimal process conditions to induce a 5 Log(CFU/ml) reduction of mesophilic microorganisms, lactic acid bacteria, yeasts and molds and a 7 Log reduction of the total coliforms. The effect of HPCD on the quality traits of coconut water were investigated by means of physical-chemical and sensory analyses and compared to the Heat Pasteurized (HP, 90 C, 1 min) and Fresh Untreated (FU) product. No differences in the basic chemical composition, vitamins and amino acids, were detected between HPCD and FU products. However, differences in the volatile compounds present in the three products were clearly distinguishable; HPCD resulted in a reduction of most of the volatile fractions while HP induced the formation of compounds with a toasted and malty aroma. Nevertheless, few sensory differences were perceived between the FU and the HPCD coconut water, and both were clearly differentiated from the HP product.

The oxytocin receptor (OTR) plays a major role in the control of male sexual responses. Antagonists of the OTR have been reported to inhibit ejaculation in animal models and serve as a potential treatment for premature ejaculation (PE). Herein, we describe a novel scaffold featuring an aryl substituted 3-azabicyclo [3.1.0] hexane structure. The lead compound, SHR1653, was shown to be a highly potent OTR antagonist, which exhibited excellent selectivity over V1AR, V1BR, and V2R. This novel molecule was shown to have a favorable pharmacokinetic profile across species, as well as robust in vivo efficacy in a rat uterine contraction model. Interestingly, SHR1653 exhibited excellent blood-brain barrier penetration, which might be beneficial for the treatment of CNS-related PE.

Synthetic Route of 3301-94-8. Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 3301-94-8, Name is 6-Butyltetrahydro-2H-pyran-2-one. In a document type is Article, introducing its new discovery.

Metal oxide catalysts were studied for their selectivity for the production of a terminally unsaturated methyl ester, methyl 5-hexenoate (M5H), from a 6 carbon, 6-membered ring lactone, delta-hexalactone (DHL). A 15 wt% Cs/SiO2 catalyst had a selectivity of 55% to M5H. This selectivity was the highest of the metal oxide catalysts studied, which were Cs/SiO2, MgO, SrO, CeO2, ZrO2, Ta2O5, MgAl2O4, and a Mg?Zr mixed oxide. The Cs/SiO2 catalyst was utilized for the ring-opening of gamma-valerolactone (GVL), a 5 carbon, 5-membered ring lactone. The catalyst was 88% selective to the terminally unsaturated methyl ester, methyl 4-pentenoate (M4P). Weight hourly space velocity studies determined that the unsaturated ester distributions remained constant and no C=C double bond isomerization occurred. Liquid phase transesterification reactions with DHL and methanol and nuclear magnetic resonance spectroscopy confirmed that DHL undergoes ring-opening transesterification to produce an omega-1 hydroxy methyl ester, methyl 5-hydroxyhexanoate (M5HH). Liquid phase transesterification reactions and thermochemistry calculations established that the equilibrium for GVL transesterification with methanol was favored towards the ring-closed lactone instead of the ring-opened hydroxy ester because of the decreased ring strain of GVL compared to DHL. The difference in terminally unsaturated methyl ester selectivity between GVL and DHL manifests from the difference in ring-strain energy. DHL passes through the M5HH intermediate as a result of greater ring strain, while the production of M4P from GVL most likely occurs through a direct, concerted mechanism.
