Plants are excellent sources of secondary metabolites that have been used for the treatment human diseases. The plant Momordica cymbalaria contains different types phytochemicals like phenols, steroids, flavonoids, alkaloids and tannins. present investigation was carried out to determine bioactive compounds in parts by Gas chromatography- Mass spectroscopy (GC-MS) technique. Chromatograms vivo ...

The title pyrrole derivative compound, C(12)H(17)NO(4), was synthesized from methyl 3-oxopenta-noate by a Knorr-type reaction and contains a pyrrole ring to which two diagonal alk-oxy-carbonyl groups and two diagonal alkyl substituents are attached. The methyl-carbonyl and ethyl-carbonyl substituents are approximately co-planar with the pyrrole ring, making dihedral angles of 5.64 (2) and 3.44 ...

N-Vinylpyrroles and -indoles bearing electron-withdrawing substituents at the pyrrole ring are mercurated, with 1 equivalent of Hg(OAc)(2) in dry MeCN (20-80 °C), regioselectively at the vinyl group (yields are almost quantitative), while their congeners without electron-withdrawing functions are mercurated both at the N-vinyl group and the pyrrole ring.

In the title compound, C(18)H(14)N(2)O(3), one of the phenyl rings is almost coplanar with the pyrrole ring [dihedral angle = 2.56 (14)°], whereas the other one is tilted by 63.01 (6)° with respect to the pyrrole ring. Since the NH group is shielded from possible acceptors, this group is not involved in hydrogen bonding.

In 1956 Mauzerall and Granick (1) published a method for the calorimetric determination of a-aminoketones that depended on coupling of an a-aminoketone with acetylacetone to form a pyrrole with a free Q! position. The Ehrlich reagent, p-dimethylaminobenzaldehyde in acid, reacted at the CY position of this pyrrole to form a highly colored compound. This method made possible the determination of ...

Biological Electronic, Optical Properties, and Vibrational Analysis of 1-benzyl-4-formyl-1H-pyrrole 3carboxamide are studied by using a combination of DFT/B3LYP method and 6-311G (d, p) basis set. Optimized parameters of the title molecule are well-matched with the experiments. The NLO properties of 1-benzyl-4-formyl-1H-pyrrole 3carboxamide have been examined with the help of Polarizability...

phytochemical investigations of piper sarmentosum roxb., yielded four compounds; three amides, identified as 3-(3’,4’,5’-trimethoxyphenylpropanoyl) pyrrolidine, 3-(4’-methoxyphenylpropanoyl) pyrrole, n -(3-phenylpropanoyl) pyrrole and a sterol namely β -sitosterol . 3-(4’-methoxyphenylpropanoyl) pyrrole was found for the first time in this piper species. all chemical constituents were tested fo...

A novel 3,4,4a-trihydroxanthene-fused pyrrole 2 was synthesized by the reaction of 2,3,4,4a-tetrahydro-1H-xanthen-1-one with 3-phenyl-2H-azirine in the presence of LDA. Utilizing this pyrrole 2, a NIR BODIPY 1 (λ(abs) = 732 nm, λ(em) = 747 nm) has been prepared. The new BODIPY 1 was stable, non-cytotoxic, and suited to labeling living cells for imaging assay in the NIR region.

A pencil graphite electrode (PGE) was modified by the electropolymerization of pyrrole-1-carboxylic acid (Py-CO2) to form a sensing film poly(pyrrole-1-carboxylic acid) (PPy-CO2) for sensitive determination Pb2+ and Cd2+ differential pulse anodic stripping voltammetry (DPASV). The porous structure PPy-CO2 uniformly distributes carboxylate group throughout coating selectively coordinate preconce...
