Indole derivatives have been the focus of many researchers in the study of pharmaceutical compounds for many years. Researchers have investigated the effect of carboxamide moiety at positions 2 and 3, giving unique inhibitory properties to these compounds. The presence of carboxamide moiety in indole derivatives causes hydrogen bonds with a variety of enzymes and proteins, which in many cases, inhibits their activity. In this review, synthetic strategies of indole 2 and 3-carboxamide derivatives, the type, and mode of interaction of these derivatives against HLGP, HIV-1, renin enzyme, and structure-activity studies of these compounds were investigated. It is hoped that indole scaffolds will be tested in the future for maximum activity in pharmacological compounds. [GRAPHICS] .

3141-26-2, Name is 3,4-Dibromothiophene, molecular formula is C4H2Br2S, Recommanded Product: 3141-26-2, belongs to indole-building-block compound, is a common compound. In a patnet, author is Abiedalla, Younis, once mentioned the new application about 3141-26-2.

The compounds in this study are the six regioisomeric 2-, 3-, 4-, 5-, 6- and 7-formyl indoles and the corresponding six regioisomeric N-n-pentylindole aldehydes. These compounds can serve as precursor chemicals and synthetic intermediates for a number of synthetic cannabinoid drugs. These two sets (the six regioisomeric indole aldehydes as well as the six regioisomeric pentylindole aldehydes) each have identical elemental compositions and differ in the position of attachment of the aldehyde group on the indole ring. The electron ionization mass spectra for the indole aldehydes were essentially identical. However, the vapor phase infrared spectra showed differences in the absorption frequencies for the N-H and carbonyl groups based on intramolecular interactions. The associated N-H absorption band occurs as low as 3467 cm(-1) while the free band is as high as 3517 cm(-1). The aldehyde carbonyl band for the indole aldehydes varies from 1713 cm(-1) to 1686 cm(-1). Substitution of the aldehyde group on the pyrrole ring for the N-n-pentylindole aldehydes yields lower carbonyl absorption bands. The EI mass spectra for the pentylindole aldehydes are identical with little information for differentiation among these six regioisomeric compounds. The six compounds were separated on a capillary column using gas chromatography and the elution order appears to be related to the steric crowding of the indole ring substituents.

A few fluorinated 3-hydrazino-1,2,4-triazino[5,6-b] indoles (5-8) have been synthesized and screened for their herbicidal effect. Treatment of 3-hydrazino-8H/8-fluoro-1,2,4-triazino[5,6-b] indoles (3 and 4) with fluorinated acyl derivatives (A and B) yielded the rich fluorine 1,2,4-triazino indole. Structure of the products have been established by elemental analysis and spectral measurements. The presence and position of fluorine atoms have been deduced from F-19 NMR. The novel fluorinated hydrazino-1,2,4-triazino[5,6-b] indoles have been tested for post-emergent herbicidal activity against grass weed species and broadleaf weed species.

Ruthenium(II)-catalyzed facile synthesis of 3-(phenylamino)-1H-indole-2-carboxylates from anilines and diazo pyruvates promoted by FeCl3

An unprecedented synthetic route towards a variety of 3-anilino-1H-indoles is accomplished from diazo pyruvates and anilines via a domino ruthenium-catalyzed annulation and subsequent iron promoted fragmentation and rearrangement. The current strategy was amenable to deliver diversely substituted indole esters, which were subjected to in vitro anti-cancer activity assessment using CCK-8 assay. Compound 4i displayed the best inhibition activity with IC50 value of 0.05 mu M, triggering the initiation towards discovering promising lead compounds in the future.
