On the interaction of 2-amino-7-phosphono-heptanoic acid and quinolinic acid in mice
European Journal of Pharmacology, 1983It is shown that (a) peripheral injections of quinolinic acid cause neuronal excitation with a latency much less than that of convulsions due to quinolinic acid and (b) peripherally injected 2-amino-7-phosphono-heptanoic acid (2APH) does antagonise neuronal excitation due to quinolinic acid applied locally by microiontophoresis.

Extraction of Lanthanides with Mixtures of Crown Ethers and Heptanoic Acid
Solvent Extraction and Ion Exchange, 2003Abstract The liquid extraction of some lanthanides (Pr, Gd, and Yb) with mixtures of heptanoic acid H3C(CH2)5COOH (HA) and crown ethers (B) benzo‐15‐crown‐5 (B15C5), dicyclohexano‐18‐crown‐6 (DH18C6), and 18‐crown‐6 (18C6) in carbon tetrachloride (CCl4) as a solvent from aqueous chloride medium at constant ionic strength μ = 0.1 is investigated.

Extraction of manganese(II) from ammonium chloride solutions with heptanoic acid
Hydrometallurgy, 1989Abstract The distribution of Mn(II) between aqueous 1.0 M NH4Cl solution and heptanoic acid solutions in carbon tetrachloride was studied. Regression analysis methods were used to determine the species present in the organic phase. It has been established that the composition of these species depends on the total manganese(II) concentration in the ...

Vibrational Davydov splitting in 7-(2-anthryl)-1-heptanoic acid Langmuir-Blodgett films
Thin Solid Films, 1988The IR absorption spectrum of Langmuir-Blodgett multilayers of 7-(2-anthryl)-1-heptanoic acid (I) deposited onto CaF2 substrates was recorded between 1800 cm−1 and 1400 cm−1 using normally incident polarized light. For multilayers deposited from a pH 4.9 subphase the CO stretch at approximately 1700 cm−1 shows a polarization similar to that observed ...

A series of disubstituted thiazoles, functionalized with the essential 3,5-dihydroxy-6-heptenoic or heptanoic chain, were prepared and evaluated for their ability to inhibit the enzyme HMG-CoA reductase in vitro. All the synthesized compounds 46-61 showed a moderate inhibitory potency.

In the normal heart, there is loss of citric acid cycle (CAC) intermediates that is matched by the entry of intermediates from outside the cycle, a process termed anaplerosis. Previous in vitro studies suggest that supplementation with anaplerotic substrates improves cardiac function during myocardial ischemia and/or reperfusion.

QSAR study of HMGR inhibitors: 7-(heteroaryl)-3,5-dihydroxy-6-heptenoic (-heptanoic) acids.
Drug design and discovery, 1993The 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) inhibitory activity of pyridine- and pyrimidine-substituted 3,5-dihydroxyhept-6(E)-enoic acids and 7-(1H-pyrrol-3-yl)-substituted-3,5-dihydroxyhept-6(E)-enoic (-heptanoic) acids was quantitatively analysed using hydrophobicity, molar refractivity, electronic and Verloop's steric parameters.
