Lincomycin (863 units per mg), acetylsalicylic (13, >98%), 3-aminobenzoic (15, 98%), 4-amino-2chlorobenzoic (22, 97%), 4-amino-2-hydroxybenzoic (26, 99%), benzoic (6, >97%), 2-chlorobenzoic (8, 98%), trans-cinnamic (44, 99%), 4-coumaric (43, 98%), 2,3-dichlorobenzoic (40, 97%), 2,5-dichlorobenzoic (36, 97%), 3,4-dichlorobenzoic (31, 99%), 3,4-dihydroxybenzoic (30, 97%), 3,4-dimethoxybenzoic (32...

for the first time in the present study the effects of vanillin, vanillyl alcohol, vanillic acid, as well as the newly synthesized vanillin derivative, bis-vanillin, were investigated on the oxidation of dopamine hydrochloride by mushroom tyrosinase. among them, vanillin and bis-vanillin act as activators, while vanillyl alcohol and vanillic acid exhibited inhibitory effects, the ic50 values be...

The formation of C−C-bonds constitutes one the most fundamental synthetic operations in organic chemistry. nucleophilic addition preformed organometallic reagents to an electrophilic carbonyl functionality represents a classical method for selective construction C−C-bond. However, synthesis and utilization reagent is associated with unfavorable environmental profile. Herein, we disclose Palladi...

We have observed a markedly decreased formation of hippuric acid after benzoic acid load in patients with typical Friedreich's Ataxia compared to normal control subjects. Since there is evidence for normal or even enhanced tauro-conjugation in the bile of patients with this disease, with a decreased G/T ratio, it is unlikely that co-factor or enzyme concentrations are the cause of this defect. ...

A novel series of double hydrogen bonded liquid crystals have been isolated. Hydrogen bond was formed between non mesogen chiral ingredient levo tartaric acid (LTA) and mesogenic undecyloxy benzoic acids (11BA) Thermal and electrical properties exhibited by levo tartaric acid and undecyloxy benzoic acid (LTA+11BA) were discussed. Interesting feature of the present investigation was observation ...

A new protocol for the decarboxylative Heck vinylation of benzoic acids is disclosed. In the presence of a catalyst system generated in situ from Pd(OAc)₂ (2 mol %), CuF₂ (2 equiv), and benzoquinone (0.5 equiv) in NMP, a wide range of olefins were coupled with various 2-nitrobenzoates at 130 ° C with the release of carbon dioxide to afford the corresponding vinyl arenes in good yields.

In this work, the reaction of derivatives benzoic acid containing substituents in aromatic ring (1a-o) with 2-chloro-4,6dimethoxy-1,3,5-triazine (4) presence N-methylmorpholine (6) has been synthesized active triazine esters carboxylic acids (3a-o). These compounds obtained potassium butylate (7) vinyl acetate (2) have formed corresponding (5a-o). The electronic effect substitutor affects on ca...
