Abstract:

The mixed anhydride of 5-(aminosulfonyl)-2-methoxybenzoic acid (VII) and monoethyl carbonate reacted with benzylamine, 1-methylpiperazine, and 1-benzylpiperazine to give the 5-(aminosulfonyl)-2-methoxybenzamides II, IV, and V. Heating the ethyl ester X with 4-amino-1-methyl-piperidine resulted in the amide III. Reaction of 5-(chlorosulfonyl)-2-methoxybenzoyl chloride (XI) with 1-benzylpiperazine afforded 5-(4-benzylpiperazinosulfonyl)-2-methoxybenzoic acid 4-benzylpiperazide (VI). Compounds II-VI are analogues of the antidopaminergic and antiemetic agent sulpiride (I) but only benzylpiperazide

Abstract:

A study on the kinetics of inhibitory effect of 4-hydroxy-3-methoxybenzoic acid on the monophenol- and diphenol-oxidation activity of mushroom tyrosinase has been carried out using enzymological kinetic analysis method in a Na2HPO4-NaH2PO4 buffer solution (pH=6.8) at 30 °C. The results show that 4-hydroxy-3-methoxybenzoic acid efficiently can inhibit both monophenol- and diphenol-oxidation activity of mushroom tyrosinase under experiment conditions. Concentrations of 4-hydroxy-3-methoxybenzoic acid leading to 50 % inhibition rate (IC50) on monophenol- and diphenol-oxidation activity were calcu

Investigation of chemical compounds from the butanol soluble layer of the traditional herb Hovenia dulcis has led to the isolation of a new compound, identified as 2-methoxybenzoic acid-5- O-α-L-rhamnopyranoside (1), along with three known compounds, syringic acid-4- O-α-L-rhamnopyranoside (2), syringic acid (3), and vanillic acid (4). Their chemical structures were established from the interpretation of 2D NMR spectroscopic and the high-resolution mass data.

Abstract:

The vibrational spectra of p-methoxybenzoic acid (anisic acid) were calculated and compared with the experimental spectra. All measured bands in the IR and Raman spectra were interpreted in terms of calculated vibrations from the AM1 and 4–21G* methods, and their frequencies were correlated. Several scale coefficients were used to improve the theoretical spectra. The optimum geometric parameters were also computed with the AM1 semiempirical method and with the 4–21G* ab initio procedure.

Abstract:

Vanillic acid (4-hydroxy-3-methoxybenzoic acid) is a dihydroxybenzoic acid derivative used as a flavoring agent. It is used in the synthesis of various active pharmaceutical ingredients such as Etamivan, Modecainide, Brovanexine, Vanitiolide, Vanyldisulfamide etc. In this paper, novel ester / hybrid derivative of vanillic acid was synthesized. This combinatorial synthesis of novel vanallic ester / hybrid derivative can be a useful approach to generate potent chemotherapeutic agents in developing new drug candidates.

Abstract:

Evaluation of several herbicides for the control of alfalfa and red clover in a legume-corn no-till system showed that spring burn-down of the legumes may be preferred to fall burn-down. Spring application gave similar or greater control of these species than fall applications. Treatments with dicamba (3,6-dichloro-2-methoxybenzoic acid) at 0.6 kg ha−1 were the most effective in controlling red clover and alfalfa. Key words: Weed control, perennial legumes, spring application, fall application

FT-IR (in solid state and solution), FT-Raman, UV and1H,13C NMR spectra of p-methoxybenzoic (p-anisic) acid and lithium, sodium, potassium, rubidium and caesiump-methoxybenzoates (p-anisates) were registered, assigned and analyzed. The structures of anisic acid and Li, Na and Kp-anisates were optimised at the B3LYP/6-311++G** level. The IR spectra and NPA, ChelpG and MK atomic charges were calculated. The effect of metal ions on the electronic charge distribution in ligand was discussed.

Abstract:

A new spiroalkaloid, 7-epi-javaniside (1), was isolated from the Cameroonian plant Pauridiantha callicarpoides, along with seven known compounds viz., javaniside (2), sweroside (3), hymexelsin (4), scopoletin (5), 7,7`-dihydroxy-6,6`-dimethoxy-8,8`-biscoumarin (6), 7,7`-dihydroxy-6,6`- dimethoxy-3,3`-biscoumarin (7), and 4-hydroxy-3-methoxybenzoic acid (8). The structures of the new alkaloid, as well as those of the known compounds, were elucidated by detailed spectroscopic analysis including 1D and 2D NMR and by comparison with the literature data for related compounds.

Abstract:

An increasing eco-consciousness among peoples has been shifting the use of natural dyes for textile dyeing and in other realms too as food, pharmaceuticals and cosmetics. The present study was focussed on aqueous extraction of natural dye from the pod husk of Senna siamea (Lam.) H.S. Irwin & Barneby, its characterization through spectroscopic (UVVIS and FT-IR) and chromatographic (GC-MS/ LC-MS) technique. It was noticed that the percent recovery was 16%, while FTIR results indicates different functional groups present in the dye, total 16 constituents were identified in the GC-MS analysis

Abstract:

A new prenylated benzoic acid derivative, named myrsicorianol (1), was isolated from the fruits of Myrsine coriacea and its structure was determined by spectral analysis, including 1D- and 2D-NMR experiments. Myrsinoic acid A and a mixture of the p-benzoquinones, embelin, rapanone and 2,5-dihydroxy-3-pentadecyl-1,4-benzoquinone (homorapanone) were also obtained from the fruits, whilst the bark afforded myrsinoic acid A, myrsinoic acid B, 3-(3′,7′-dimethyl-2′,6′-octadienyl)-4-hydroxybenzoic acid and 3-(3′,7′-dimethyl-2′,6′-octadienyl)-4-methoxybenzoic acid.
