In particular, compounds of the invention have antibacterial activity and/or are capable of re-sensitizing methicillin-resistant Staphylococcus aureus to a P-lactam antibiotic or a combination of a P-lactam antibiotic and a P-lactamase inhibitor. The present invention also relates to a method for producing and using said compounds.
Gram-scale, chemoselective synthesis of N-[2-(5-hydroxy-1H-indol-3-yl)ethyl]-2-oxopiperidine-3-carboxamide (HIOC)

N-[2-(5-Hydroxy-1H-indol-3-yl)ethyl]-2-oxopiperidine-3-carboxamide (HIOC) is a potent activator of the TrkB receptor in mammalian neurons and of interest because of its potential therapeutic uses. In the absence of a commercial supply of HIOC, we sought to produce several grams of material. However, a synthesis of HIOC has never been published. Herein we report the preparation of HIOC by the chemoselective N-acylation of serotonin, without using blocking groups in the key acylation step.

Evodiamine and its derivatives have an asymmetric center at the C13b position. Herein, isomers of evodiamine derivatives 2 and 3 were obtained by straightforward asymmetric total synthesis. Their inhibitory activities toward topoisomerases I and II and th

Evodiamine is a quinazolinocarboline alkaloid isolated from the fruits of traditional Chinese herb Evodiae fructus. Previously, we identified N13-substituted evodiamine derivatives as potent topoisomerase I inhibitors by structure-based virtual screening and lead optimization. Herein, a library of novel evodiamine derivatives bearing various substitutions or modified scaffold were synthesized. Among them, a number of evodiamine derivatives showed substantial increase of the antitumor activity, with GI50 values lower than 3 nM. Moreover, these highly potent compounds can effectively induce the apoptosis of A549 cells. Interestingly, further computational target prediction calculations in combination with biological assays confirmed that the evodiamine derivatives acted by dual inhibition of topoisomerases I and II. Moreover, several hydroxyl derivatives, such as 10-hydroxyl evodiamine (10j) and 3-amino-10-hydroxyl evodiamine (18g), also showed good in vivo antitumor efficacy and low toxicity at the dose of 1 mg/kg or 2 mg/kg. They represent promising candidates for the development of novel antitumor agents.

The first total synthesis of the chlorinated 1-oxo-β-carboline alkaloid bauerine C based on a Japp-Klingemann reaction is reported. An intermediate of this synthesis was converted to the fully aromatic β-carboline bauerine B, and the related alkaloid baue
Syntheses of 7-fluoro- and 6,7-difluoroserotonin and 7-fluoro- and 6,7-difluoromelatonin

The Abramovitch adaption of the Fischer indole synthesis gave low yields of 7-fluoro-5-methoxytryptamine due in part to decomposition during the required decarboxylation step. Therefore, 7-fluoro- and 6,7-difluoro-5-methoxytryptamines were prepared by rea

Novel inhibitors of acetyl- and butyrylcholinesterase derived from the alkaloids dehydroevodiamine and rutaecarpine
Decker, Michael
, p. 305 - 313 (2007/10/03)
Derived from the structures of the alkaloids rutaecarpine and dehydroevodiamine (DHED), and the long-known acetylcholinesterase (AChE) inhibitor tacrine, respectively, novel compounds were synthesised, including: 13-methyl-5,8-dihydro-6H-isoquino[1,2-b]quinazolin-13-ium chloride (12), (8Z)-5,6-dihydro-8H-isoquino[1,2-b]quinazolin-8-imine (13), 5,8-dihydro-6H- isoquino[1,2-b]quinazoline (15a), 13-methyl-5,8-dihydro-6H-isoquino[1,2-b] quinazolin-13-ium chloride (16), 5,7,8,13-tetrahydroindolo [2′,3′:3, 4]pyrido[2,1-b]quinazoline (17), and N-(2-phenylethyl)-N-[(12Z)-7,8,9,10- tetrahydroazepino [2,1-b]quinazolin-12(6H)-ylidene]amine (20), respectively. In a first step to evaluate their possible applicability for antiamnesic therapy, the inhibition of AChE and butyrylcholinesterase (BChE) were determined: compounds 13, 15a, 17, and 20 are moderate or strong inhibitors of ChE, the latter two compounds show a 10-fold higher affinity to BChE. Compound 12 is a moderate inhibitor of AChE showing selectivity towards this enzyme. (Chemical presented)
