New heterocyclic derivatives of cyclopropane dicarboxylic acid comprising thiadiazole and 1,2,4-triazole moieties are reported. Reaction of 1,1-cyclopropane dicarboxylic acid (1) with thiosemicarbazide and phosphorous oxychloride resulted in 1,1-bis (2-amino-1,3,4-thiadiazol-5- yl)cyclopropane (2). Cyclopropane dicarboxylic acid thiosemicarbazide (6) was converted into 1,1-bis(3-thio-4H-1,2,4-t...

microwave irradiation is used in the synthesis of four tricyclic chromanones 11-14. the chromanone 14 and 12 are selectively formed thermally and under microwave in the presence of polyphosphoric acid (ppa) from the same dicarboxylic acid 9, respectively. the crystal structures of the two diacids are also reported. the corresponding ortho and meta isomers of diacids crystallize in the space gro...

Calcium salts of analogues of dipicolinic acid were substituted for calcium dipicolinate in tests of germination of spores of Bacillus megaferium ATCC 10778. Only 4Hpyran-2,6-dicarboxylic acid was as active as dipicolinic acid. 3-Methyldipicolinic acid and 4-methyl-4H-pyran-2, B-dicarboxylic acid were active but the germination proceeded less rapidly. In the presence of a threshold concentratio...

Dicarboxylic aciduria caused by enhanced or inhibited fatty acid metabolism is usually described as increased urinary excretion of saturated medium-chain dicarboxylic acids, such as adipic, suberic, and sebacic acids. Besides these saturated acids, increased excretion of unsaturated dicarboxylic acids is also observed. However, the structural identities of these unsaturated dicarboxylic acids a...

1-Aminocyclopentane-trans-1,3-dicarboxylic acid, an agonist of the metabotropic glutamate receptors 1, 2, 3 and 5, prevents neurotoxicity of glutamate and of N-methyl-D-aspartate in primary cultures of cerebellar neurons. The aim of this work was to assess which of the metabotropic glutamate receptors (mGluRs) is responsible for the protective effect. We tested the protective effects of selecti...

Dicarboxylic acids are prominent features of several diseases, including Reye's syndrome and inborn errors of mitochondrial and peroxisomal fatty acid oxidation. Moreover, dicarboxylic acids are potentially toxic to cellular processes. Previous studies [Tonsgard, Mendelson & Meredith (1988) J. Clin. Invest. 82, 1567-1573] demonstrated that long-chain dicarboxylic acids have a single high-affini...
