A series of monomeric and dimeric FeIII complexes bearing benzoic hydroxamates as O,O-chelates has been prepared and characterized by elemental analysis, IR spectroscopy, UV-Vis spectroscopy, electrospray ionization mass spectrometry (ESI-MS), cyclic voltammetry, EPR spectroscopy and for some examples by X-ray diffraction analysis. The stability of the synthesized complexes in pure water and seawater was monitored over 24 h by means of UV-Vis spectrometry. The ability to release iron from the synthesized model complexes has been investigated with algae growth experiments.
NOVEL BENZAMIDE DERIVATIVE AND USE THEREOF
-
Paragraph 0065-0066, (2014/10/16)
Disclosed are a novel benzamide derivative and pharmaceutical use thereof, and more particularly, a novel benzamide derivative having a structure of Formula 1 or pharmaceutically acceptable salts thereof, and a composition for prevention or treatment of pain or itching including the above material. The novel benzamide derivative and pharmaceutically acceptable salt thereof according to the present invention exhibit excellent pain-suppressive effect and, in particular, pain-suppressive effect in not only a neuropathic animal model but also other models such as a formalin model, and therefore, may be used in suppression of different pains such as nociceptive pain, chronic pain, etc. Further, since it was demonstrated that the present invention displays anti-pruritic efficacy even in an itching model, to which a mechanism and treatment concept established with respect to pain is applied, the present invention may also be effectively used in radical treatment of atopic dermatitis by applying the inventive product to an anti-pruritic composition in order to suppress an initial itching stage and treat symptoms thereof, thus preventing skin damage or inflammation after the scratching stage.

supporting information, p. 4540 - 4543 (2013/08/23)
Deprotection of allyl/benzyl aryl ethers was achieved chemoselectively. The mild and inexpensive reagent combination of NiCl2·6H 2O/NaBH4 in methanol afforded the products in high yields, within a reaction time of 5-10 min.

, p. 1663 - 1667 (2008/12/21)
A series of 3,5-dialkoxy-4-hydroxycinnamamides 6 and 7 was synthesized, and their antioxidant activity was assessed using the thiobarbituric acid reactive substance (TBARS) assay. Interestingly, cinnamamides with longer alkoxy groups on the C-3 and C-5 positions display enhanced inhibition, and most of the compounds in the series tested exhibit excellent lipid peroxidation inhibitory activities. Some cinamamides bearing hexyloxy or 2,6-di-tert-butyl-4-methyl phenol groups have submicromolar inhibitory activities.

To obtain effective and safe topical depigmenting agents, we synthesized hydroxybenzoates, alkoxybenzoates, and 3,4,5-trimethoxycinnamate containing a thymol moiety and screened then for high-level inhibitory activity against melanin synthesis in cultured melanocytes. Eight compounds were tested for their depigmenting effect and cytotoxicity using a murine melanocyte cell line. We found that 3,4,5-trialkoxybenzoates and 3,4,5-trimethoxycinnamate, synthesized by conjugating 3,4,5-trialkoxybenzoic acids and 3,4,5-trimethoxycinnmic acid with thymol, showed a potent depigmenting effect and low cytotoxicity. Compound 4h, 5-methyl-2-(methylethyl)phenyl (2E)-3-(3,4,5-trimethoxyphenyl)prop-2-enoate, showed the most potent depigmenting effect (IC50=10 μM) with low cytotoxicity (IC50=200 μM).

, p. 902 - 908 (2007/10/03)
Phytochemical reinvestigation on Ligularia nelumbifolia afforded four novel sinapyl alcohol analogues named nelumols B-E (1-4) and three known sinapyl alcohol derivatives (5-7). Their structures were elucidated by NMR techniques. Total syntheses of cytotoxic geranyloxy sinapyl alcohol (6) and geranyloxy sinapyl aldehyde (7) were carried out via two different paths. The 4-O-benzyl-substituted analogues (20 and 27) as well as the 4-O-(2-methylbutenyl) derivatives (34 and 35) were also synthesized. The cytotoxicities of 6 and 7 were measured using A-549, HL-60, and KB cancer cell lines.
