A series of chiral oxazino-indoles have been synthesized via a key intermolecular oxa-Pictet–Spengler reaction. These compounds exhibited significant and selective neuroprotective effects against Aβ25–35-induced neuronal damage. This is the first report of evaluating the influence of chiral diversity of oxazino-indoles on their neuroprotective activities, with the structure–activity relationship been analyzed. The highly active compounds 3f, 3g, 4g, 4h, and 6b all performed over 90% cell protection, providing a new direction for the development of neuroprotective agents against Alzheimer's disease.

The synthesis and spectral properties of new radioiodinated indolealkylamines like 2-[131 I]-iodo-N,N-dimethyltryptamine, 2-[131 I]-iodo-N-methyltryptamine, 2-[131 I]-iodo-5-methoxy-N,N-dimethyltryptamine, 2-[131 I]-iodo-5-hydroxy-N,N-dimethyltryptamine (2-[131 I]-iodo-bufotenine), and 2-[131I]-iodo-tryptamine and the known 2-[131I]-iodo-N-acetyl-5-methoxy-tryptamine (2-[131I]-iodo-melatonine) are described herein. These were synthesized by a high-yield novel method, and their spectral properties are fully described. These compounds are of biological importance and can be used for brain mapping with SPECT technology.

Herein, we presented Ru-SNS complex that serves as a useful catalyst for C-3 alkylation of 1H-indoles with various aliphatic primary and secondary alcohols including cyclic alcohols as well as benzylic alcohols. The selective synthesis of bisindolylmethane derivatives is also achieved from the same set of indole and alcohol just by altering the reaction parameters. Furthermore, the sustainable synthesis of C-3 alkylated indoles directly from 2-(2-nitrophenyl)ethan-1-ol and alcohols catalysed by a Ru-complex via “borrowing hydrogen” strategy is reported. This protocol provides an atom-economical sustainable route to access structurally important compounds like arundine, vibrindole A and tryptamine based derivatives. (Figure presented.).

Dunlap, Lee E.,Azinfar, Arya,Ly, Calvin,Cameron, Lindsay P.,Viswanathan, Jayashri,Tombari, Robert J.,Myers-Turnbull, Douglas,Taylor, Jack C.,Grodzki, Ana Cristina,Lein, Pamela J.,Kokel, David,Olson, David E.

Ketamine, N,N-dimethyltryptamine (DMT), and other psychoplastogens possess enormous potential as neurotherapeutics due to their ability to potently promote neuronal growth. Here, we report the first-ever structure-Activity relationship study with the explicit goal of identifying novel psychoplastogens. We have discovered several key features of the psychoplastogenic pharmacophore and used this information to develop N,N-dimethylaminoisotryptamine (isoDMT) psychoplastogens that are easier to synthesize, have improved physicochemical properties, and possess reduced hallucinogenic potential as compared to their DMT counterparts.

5-Hydroxytryptamine 6 receptors (5-HT6R) are being perceived as the possible target for treatment of cognitive disorders as well as obesity. The present article deals with the design, synthesis, in vitro binding and structureactivity relationship of a novel series of tetracyclic tryptamines with the rigidized N-arylsulphonyl, N-arylcarbonyl and N-benzyl substituents as 5-HT6 receptor ligands. The chiral sulphonyl derivatives 15a and 17a showed high affinity at 5-HT6R with the Ki of 23.4 and 20.5nM, respectively. The lead compound from the series 15a has acceptable ADME properties, adequate brain penetration and is active in animal models of cognition like Novel Object Recognition Task (NORT) and water maze.
Novel 5-HT7 receptor inverse agonists. Synthesis and molecular modeling of arylpiperazine- and 1,2,3,4-tetrahydroisoquinoline-based arylsulfonamides.

A series of arylpiperazine- and 1,2,3,4-tetrahydroisoquinoline-based arylsulfonamides was synthesized and evaluated for their interactions with the constitutively active 5-HT7 receptor. Effects on basal adenylate cyclase activity were measured using HEK-293 cells expressing the rat 5-HT7. All ligands produced a decrease of adenylate cyclase activity, indicative of their inverse agonism. Additionally, computational studies with a set of 22 inverse agonists, including these novel inverse agonists and inverse agonists known from literature, resulted in a pharmacophore model and a CoMFA model (R2 = 0.97, SE = 0.18). Docking of inverse agonists at the binding site of a model of the helical parts of the 5-HT7 receptor, based on the alpha carbon template for 7-TM GPCRs, revealed interesting molecular interactions and a possible explanation for observed structure-activity relationships.
