This work reports the design and synthesis of novel alkylamides, characterized by a dibenzo[a,d] cycloheptene nucleus, as melatonin (MLT) receptor ligands. The tricyclic scaffold was chosen on the basis of previous quantitative structure-activity studies on MT1 and MT2 antagonists, relating selective MT2 antagonism to the presence of an aromatic substituent out of the plane of the MLT indole ring. Some dibenzo seven-membered structures were thus selected because of the noncoplanar arrangement of their benzene rings, and an alkylamide chain was introduced to fit the requirements for MLT receptor binding, namely, dibenzocycloheptenes with an acylaminoalkyl side chain at position 10 and dibenzoazepines with this side chain originating from the nitrogen atom bridging the two phenyl rings. Binding affinity at human cloned MT1 and MT2 receptors was measured by 2[125I] iodomelatonin displacement assay and intrinsic activity by the GTPgammaS test. The majority of the compounds were characterized by higher affinity at the MT2 than at the MT 1 receptor and by very low intrinsic activity values, thus confirming the importance of the noncoplanar arrangement of the two aromatic rings for selective MT2 antagonism. Dibenzocycloheptenes generally displayed higher MT1 and MT2 affinity than dibenzoazepines. N-(8-Methoxy-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-10-ylmethyl)propionamide (4c) and -butyramide (4d) were the most selective MT2 receptor antagonists of the series, with MT2 receptor affinity comparable to that of melatonin and as such among the highest reported in the literature for MLT receptor antagonists. The acetamide derivative 4b produced a noticeable reduction of GTPgammaS binding at MT2 receptor, thus being among the few inverse agonists described.

This research presents an efficient technique to enhance the catalytic activity, surface area and total basicity of CaO with hydration-dehydration process to be the catalyst for the transesterification of palm oil to biodiesel. The catalytic performance of the resulted catalyst was tested via transesterification reaction of palm oil at room temperature (30 ± 2 C) and was compared against commercial CaO and CaO derived from natural calcium carbonate sources. Under the optimal reaction conditions (catalyst loading of 5 wt%, methanol to oil molar ratio 12:1), FAME yields were approximately 94% for CaOHY and 60.5%, 55.3%, 49.5% and 51.4% for CaOcom, CaOegg, CaOgol and CaOriv as catalysts, respectively. Catalyst reusability and scaling up of biodiesel production from 50 mL to 1.5 L were also investigated. The obtained biodiesel product after purification and treatment process showed high quality fuel properties within the range of biodiesel standard and similar with high-speed diesel. Furthermore, the used CaOHY as a solid heterogeneous catalyst at room temperature was not only low-cost but also environmentally-friendly, showing a high potential in the biodiesel production.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 496-41-3, Benzofuran-2-carboxylic acid, introducing its new discovery.

Imidazolidine and 1,4-diazepane analogs of N-(2-benzofuranyl)methyl- N?-(4-alkoxybenzyl)piperazines were prepared to explore the effect of ring contraction and expansion on sigma receptor affinity and subtype selectivity within a series of cyclic diamines. In vitro receptor binding assays revealed that all cyclic vicinal diamines possessed affinity and selectivity for sigma1 receptors. The imidazolidines possessed nanomolar sigma1 affinities (Ki = 6.45-53.5 nM), and relatively low levels of subtype selectivity (sigma2/sigma1 = 58-237). However, the piperazines and diazepanes achieved picomolar sigma1 interactions, with Ki ranges of 0.05-10.28 and 0.10-0.194 nM, respectively. Moreover, the piperazines and diazepanes showed excellent discrimination over the sigma2 receptor, with sigma1 selectivities of 143-16140 and 220-11542, respectively.

Phenol is commercially produced through cumene hydroperoxide (CHP) cleavage in kettle reactor, having the disadvantages of hazard potential, low selectivity, low efficiency and complicated process. In the study, microchannel reactor has been introduced into the decomposition using sulfuric acid as the catalyst. The influences of various reaction conditions, including temperature, the ratio of sulfuric acid/CHP and residence time, on the reaction have been studied. Compared with kettle reactor, the present process can afford almost quantitative yield of phenol with reduced acid amount and shortened reaction time under higher reaction temperature. The microchannel process can also provide higher security of CHP cleavage. The microtechnology probably gives an alternative protocol for the production of phenol through CHP decomposition. In addition, the possible main reaction pathways for the CHP cleavage in microchannel reactor have been discussed according to the obtained results.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 4265-25-2, and how the biochemistry of the body works.Related Products of 4265-25-2

The free fatty acid receptor 1 (FFA1/GPR40) is a novel antidiabetic target based on particular mechanism in enhancing glucose-stimulated insulin secretion. Most of reported FFA1 agonists, however, have been suffered from relatively high lipophilicity and molecular weight. Aiming to develop potent agonists with improved physicochemical property, 25 compounds containing triazole scaffold and various carboxylic acid fragments were synthesized via the click chemistry. Among them, the optimal lead compound 26 with relatively low lipophicity (Log D7.4 = 1.95) and molecular weight (Mw = 391.78) exhibited a considerable FFA1 agonistic activity (36.15%). In addition, compound 26 revealed a significant improvement in the glucose tolerance with a 21.4% and 14.2% reduction of glucose AUC0?2hin normal ICR mice and type 2 diabetic C57BL/6 mice, respectively. All of these results demonstrated that compound 26 was considered to be a promising lead compound suitable for further optimization.
