Syntheses of 1-Hydroxytryptamines and Serotonins Having Fattyacyl or (E)-3-Phenylpropenoyl Derivatives as an Nb-Substituent, and a Novel Homologation on the 3-Substituent of the 1-Hydroxytryptamines upon Treatment with Diazomethane
摘要:
1-Hydroxytryptamines (6a-f) having (E)-3-phenyl-, (E)-3-(4-hydroxypheny)-, (E)-3-(4-hydroxy-3-methoxyphenyl)propenoyl, octanoyl, hexadecanoyl, and docosanoyl group as a Nb-substituent are prepared for the first time. Preparations of serotonins (2a- c, e) from the corresponding 1-hydroxytryptamines (6a- c, e) are also reported. A novel homologation on the 3-substituent of 1-hydroxytryptamines is discovered upon treatment with diazomethane in chloroform or dichloromethane.

compounds demonstrated in-vitro inhibitory activities against acetyl cholinesterase (AChE) and butyryl cholinesterase (BChE). Among of these synthesized compounds, (E)-N-(2-(1H-indol-3-yl)ethyl)-3-(3,4-dimethoxyphenyl)acrylamide (5q) demonstrated the most potent AChE inhibitory activity (IC 50 = 11.51 μM) and (E)- N -(2-(1H-indol-3-yl)ethyl)-3-(2-chlorophenyl)acrylamide (5b) were the best anti-BChE (IC

The present invention relates to a method for synthesising amides that is of general applicability. The method may be performed in vitro or in vivo. Cell lines for use in the in vivo methods also form aspects of the invention. The method for synthesising a non-natural amide comprises: a. reaction of a carboxylic acid with a naturally occurring CoA ligase or a variant thereof; and b. reaction of the product of step a with an amine in the presence of a naturally occurring acyltransferase or a variant thereof; with the proviso that where the CoA ligase and acyltransferase are both naturally occurring, they are not derived from the same source species and do not act sequentially in a metabolic pathway; and with the proviso that the non-natural product is not N-(E)-p-coumaroyl-3-hydroxyanthranilic acid or N-(E)-p-caffeoyl-3-hydroxyanthranilic acid. Further, a method for producing an active pharmaceutical ingredient by the aforementioned method and host cells for carrying out said methods are envisaged.

the synthesis of a series of 29 substituted N-phenylethyl cinnamamides through the direct amidation of a variety of cinnamic acids with a broad range of phenylethylamines promoted by tris-(2,2,2-trifluoroethyl) borate (B(OCH2CF3)3) in excellent yields and under mild reaction conditions. Then, the toxicological profile of the prepared compounds was studied through in silico computational methods, analyzing
An intermolecular aza-double Michael reaction leading to functionalized piperidin-2-ones from simple starting materials has been developed. The method allows alpha,beta-unsaturated amides to be used as a synthon of the piperidine nucleus. In addition, the utility of this methodology is demonstrated by its application to a formal synthesis of the indolo[2,3-a]quinolizidine alkaloids, (+/-)-deplancheine, (+/-)-tacamonine, and the antidepressant paroxetine.

Some compounds, characterized by phenylethenyl moiety, such as methyl cinnamate and caffeic acid phenethyl ester, are able to inhibit C. albicans biofilm formation. On these bases, and as a consequence of our previous work, we synthesized a series of cinnamoyl ester and amide derivatives in order to evaluate them for the activity against C. albicans biofilm and planlctonically grown cells.The most active compounds 7 and 8 showed >> 50% biofilm inhibition concentrations (BMIC50) of 2 mu g/mL and 4 mu g/mL respectively, against C albicans biofilm formation; otherwise, 7 showed an interesting activity also against mature biofilm, with BMIC50 of 8 mu g/mL.
