Structure-activity studies for a novel series of tricyclic substituted hexahydrobenz[e]isoindole alpha(1A) adrenoceptor antagonists as potential agents for the symptomatic treatment of benign prostatic hyperplasia (BPH)

In search of a uroselective agent that exhibits a high level of selectivity for the alpha(1A) receptor, a novel series of tricyclic hexahydrobenz[e]isoindoles was synthesized. A generic pharmacophoric model was developed requiring the presence of a basic amine core and a fused heterocyclic side chain separated by an alkyl chain. It was shown that the 6- OMe substitution with R, R stereochemistry of the ring junction of the benz[e]isoindole and a two-carbon spacer chain were optimal. In contrast to the highly specific requirements for the benz[e]isoindole portion and linker chain, a wide variety of tricyclic fused heterocyclic attachments were tolerated with retention of potency and selectivity. In vitro functional assays for the alpha1 adrenoceptor subtypes were used to further characterize these compounds, and in vivo models of vascular vs prostatic tone were used to assess uroselectivity.

Enantioselective halocyclization using reagents tailored for chiral anion phase-transfer catalysis

A chiral anion phase-transfer system for enantioselective halogenation is described. Highly insoluble, ionic reagents were developed as electrophilic bromine and iodine sources, and application of this system to o-anilidostyrenes afforded halogenated 4H-3,1-benzoxazines with excellent yield and enantioselectivity.

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.Recommanded Product: 5394-13-8, you can also check out more blogs about5394-13-8

Synthesis and Physicochemical Properties of Dibenzo[2,3- d:2?,3?- d?]anthra[1,2- b:5,6- b?]dithiophene (DBADT) and Its Derivatives: Effect of Substituents on Their Molecular Orientation and Transistor Properties

We have synthesized dibenzo[2,3-d:2?,3?-d?]anthra[1,2-b:5,6-b?]dithiophene (DBADT) and several derivatives bearing alkyl and phenyl groups at various positions. The optical and electrochemical properties of the synthesized compounds were investigated. All the fabricated OFET devices exhibited typical p-type behavior under ambient conditions, and diphenyl-substituted analogue-based OFET devices showed excellent mobility, as high as 0.66 cm2 V-1 s-1. The surface morphology and molecular orientation in thin films were also investigated using atomic force microscopy (AFM) and two-dimensional grazing incidence X-ray diffraction (2D-GIXD). It was found that the substituents and their positions affect the molecular orbitals, molecular orientation, and morphology of the thin films, producing different FET performance.

Synthesis and cytotoxic activity of lipophilic sulphonamide derivatives of the benzo[b]thiophene 1,1-dioxide

In the search of new compounds with antineoplastic activity, we have analysed the effect of several structural modifications on the nucleus 6-benzo[b]thiophenesulphonamide 1,1-dioxide on its cytotoxic activity on tumour cells. Lipophilic substituents on the sulphonamide group significantly increased the cytoxic activity measured using a panel of human tumour cell lines. Only slight variations on cytotoxicity were obtained when the sulphonamide group occupied the position 5 of the system. The most active compound was the N-4-methoxyphenyl derivative 15, which showed GI50 values of 1-9 nM against HT-29, CCRF-CEM, K-562 and MEL-AC cells and of 200 nM against HTB-54 cells. Free access to the 3-position of the heterocyclic system seems to be required to obtain cytotoxic derivatives. Derivative 15 was also active at the same level of commercial Doxorubicine against cultured normal human lung fibroblasts.

Ir-catalyzed cascade c-h fusion of aldoxime ethers and heteroarenes: Scope and mechanisms

A concise synthesis of phenanthridine derivatives is achieved by an iridium-catalyzed direct fusion of oxime ethers and heteroarenes, which is a successful example of a cascade C-H/C-H cross-coupling/cyclization strategy for polycyclic heteroaromatic synthesis. By subtle tuning of the reaction conditions, both benzo- and simple five-membered heteroarenes are suitable substrates under similar but different conditions. The key is the right choice of a silver salt. The detailed mechanistic study discloses that the first C-H/C-H cross-coupling step involves an [IrII]-[IrIV] catalytic cycle, which needs Ag2O as the oxidant. For the second cyclization step, a radical process takes control in the reactions of benzoheteroarenes and Ag2O is required; however, a C-H cyclization functions in the reactions of simple five-membered heteroarenes involving an [IrI]-[IrIII] catalytic cycle, and AgTFA is necessary.
