Reactions of N-arylmaleimides with 3-amino-1,2,4-triazole and 2-aminobenzimidazole

Figure represented. The reaction of 3-amino-1,2,4-triazole (1) with N-arylmaleimides leads to azolopyrimidines 4 and 5. The 2-aminobenzimidazole (2) in the reaction with 3 gives the pyrimidobenzimidazoles 6. In similar conditions, the reaction of amine 2 with maleic anhydride (7) leads to formation of 2-oxo-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazole-4-carboxylic acid (8). The structures of 4, 5, 6, and 8 were proved by X-Ray and NOE NMR measurements. J. Heterocyclic Chem., (2011)

Metal-Free and Versatile Synthetic Routes to Natural and Synthetic Prodiginines from Boron Dipyrrin

Prodiginines, as a family of bacterial alkaloids, possess a number of interesting biological activities. New, concise synthetic routes for the facile preparation of both synthetic and natural prodiginines in good yields have been developed, which use BODIPY functionalization reactions, such as condensation, nucleophilic substitution, and BF2 deprotection. This new metal-free synthetic method opens the door toward a wide variety of C-ring functionalized prodiginines, including those that are not possible to obtain through current synthetic methods, for their advanced biological activities.

An overview on benzylisoquinoline derivatives with dopaminergic and serotonergic activities

Dopamine and serotonin are important neurotransmitters in the mammalian central nervous system (CNS) involved in numerous physiological and behavioural disorders such as schizophrenia, major depression, anxiety, Parkinson’s and Huntington’s diseases, and attention deficit hyperactivity disorder. Several natural and synthetic benzylisoquinoline derivatives have displayed affinity for dopamine and serotonin receptors in nanomolar or micromolar ranges. This review covers the last three decades of dopaminergic and serotonergic activities, and especially focuses on structure-activity relationships of natural and synthetic benzylisoquinoline derivatives. We have included aporphines, 1-benzyltetrahydroisoquinolines, bis-benzylisoquinolines, protoberberines, cularines and other structural analogues. Further molecular modelling calculations have been considered as important tools to not only obtain structural information of both neurotransmitter receptors, but to also identify their pharmacophore features. The development of selective potential ligands like benzylisoquinoline derivatives may help in the therapy of diseases related to CNS dysfunction.

Total Synthesis and Biological Evaluation of Hybrubin A

Here, we report the first total synthesis of hybrubin A, a bipyrrole tetramic acid alkaloid representing a new carbon framework derived from convergent (truncated red cluster and exogenous hbn cluster) biosynthetic pathways. A highly convergent synthesis was developed, employing 4-methoxy-1,5-dihydro-2H-pyrrol-2-one (13) as a single starting material to provide hybrubin A in three steps from 13 and 20.8% overall yield. As no biological activity was prescribed to hybrubin A except for a lack of cytotoxicity, we further profiled this unique alkaloid across panels of discrete molecular targets. Interestingly, hybrubin A was found to be a ligand for a variety of GPCRs with a propensity for potent binding across therapeutically relevant adenosine receptors (A1, A2a, and A3) as well as a potent activity at a kinase, FLT3. This pattern of biological activity is distinct from other related prodigiosin natural and unnatural products and is even more intriguing in the absence of cytotoxicity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 4-Methoxy-1H-pyrrol-2(5H)-one, you can also check out more blogs about69778-83-2

Chingazumianine, a novel dichlorinated alkaloid from Corydalis koidzumiana

A dichlorinated alkaloid with a novel skeleton, chingazumianine (1), was isolated from the herb Corydalis koidzumiana, and its structure elucidated by spectroscopic data and X-ray crystallographic analysis. In citratetreated human platelet-rich plasma (PRP), known compounds, i.e., protopine (2), (¡À)-tetrahydropalmatine (3), and palmatine (4), isolated from this plant, showed significant inhibition of secondary aggregation induced by adrenaline in a concentration-dependent manner, suggesting that the antiplatelet effects of these compounds is mainly due to an inhibitory effect on thromboxane formation.

Controlled Covalent Functionalization of 2 H-MoS2 with Molecular or Polymeric Adlayers

Most air-stable 2D materials are relatively inert, which makes their chemical modification difficult. In particular, in the case of MoS2, the semiconducting 2 H-MoS2 is much less reactive than its metallic counterpart, 1T-MoS2. As a consequence, there are hardly any reliable methods for the covalent modification of 2 H-MoS2. An ideal method for the chemical functionalization of such materials should be both mild, not requiring the introduction of a large number of defects, and versatile, allowing for the decoration with as many different functional groups as possible. Herein, a comprehensive study on the covalent functionalization of 2 H-MoS2 with maleimides is presented. The use of a base (Et3N) leads to the in situ formation of a succinimide polymer layer, covalently connected to MoS2. In contrast, in the absence of base, functionalization stops at the molecular level. Moreover, the functionalization protocol is mild (occurs at room temperature), fast (nearly complete in 1 h), and very flexible (11 different solvents and 10 different maleimides tested). In practical terms, the procedures described here allow for the chemist to manipulate 2 H-MoS2 in a very flexible way, decorating it with polymers or molecules, and with a wide range of functional groups for subsequent modification. Conceptually, the spurious formation of an organic polymer might be general to other methods of functionalization of 2D materials, where a large excess of molecular reagents is typically used.

Alkylene-chain effect on microwire growth and crystal packing of pi-moieties

We developed a facile approach to modulate molecular arrangement through dimerizing of pi-moieties and tuning alkylene-bridge length. Dimers of fluoranthene-fused imide (DFAI-Cns) with various lengths of alkylene chains were synthesized by a Diels-Alder reaction followed by decarbonylation. DFAI-C3 and DFAI-C5 with odd-carbon alkylene chains display stronger one-dimensional growing tendency and better crystallinity than those with even-carbon alkylene chains. Microwires of dimers with odd-carbon alkylene chains were successfully obtained, and their molecular packing was analyzed by transmission electron microscopy (TEM) and selected-area electron diffraction (SAED). Systematic investigation of their single crystal packing showed that alkylene chains with different lengths produced two kinds of molecular configurations. The V-shaped molecular configuration was observed from DFAI-C3 and DFAI-C5 with odd-carbon alkylene chains; however, the Z-shaped one was observed from DFAI-C4, DFAI-C6, and DFAI-C12 with even-carbon alkylene chains. Accordingly, we attributed the diverse microstructures and crystallinity of the dimers to their distinct molecular configurations in single crystals. In addition, a computational method was employed to demonstrate the weak intermolecular interactions in these dimers. Our investigation indicates that the introduction of bridging alkylene chains is an effective approach to modulate microwire growth and crystal packing of pi-systems in solid state.
