Methyl 6-amino-6-oxohexanoate
The title compound, C(7)H(13)NO(3), adopts an approximately planar conformation. The torsion angles in the aliphatic chain between the carbonyl group C atoms range from 172.97 (14) to 179.38 (14)° and the r.m.s. deviation of all non-H atoms is 0.059 Å. The crystal packing is dominated by two strong N-H⋯O hydrogen bonds involving the amide groups and forming R(2) (2)(8) rings and C(4) chains. Ov...
متن کاملSynthesis and biological activity of N(alpha)-[4-[N-[(3,4-dihydro-2-methyl-4-oxo-6-quinazolinyl)methyl]-N-propargylamino]phenylacetyl]-L-glutamic acid.
2-Deamino-2-methyl-N10-propargyl-5,8-dideazafolic acid (ICI 198583) is a potent inhibitor of thymidylate synthase. Its analogue, N(alpha)-[4-[N-[(3,4-dihydro-2-methyl-4-oxo-6-quinazolinyl)methyl]-N-propargylamino]phenylacetyl]-L-glutamic acid, containing p-aminophenylacetic acid residue substituting p-aminobenzoic acid residue, was synthesized. The new analogue exhibited a moderately potent thy...
متن کاملUrsodeoxycholic acid, chenodeoxycholic acid, and 7-ketolithocholic acid are primary bile acids of the guinea pig.
Guinea pig gallbladder bile contains chenodeoxycholic acid (62 +/- 5%), ursodeoxycholic acid (8 +/- 5%), and 7-ketolithocholic acid (30 +/- 5%). All three bile acids became labeled to the same specific activity within 30 min after [3H]cholesterol was injected into bile fistula guinea pigs. When a mixture of [3H]ursodeoxycholic acid and [14C]chenodeoxycholic acid was infused into another bile fi...
متن کامل2-Amino-6-methyl-1,3-benzothiazole–decanedioic acid (2/1)
Co-crystallization of 2-amino-6-methyl-1,3--benzothia-zole with deca-nedioic acid under hydro-thermal conditions afforded the title 2:1 co-crystal, 2C(8)H(8)N(2)S·C(10)H(18)O(4). The deca-nedioic acid mol-ecule is located on an inversion centre. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds connect the components into a two-dimensional wave-like layer structure extending parall...
متن کامل2-Amino-6-methyl-1,3-benzothiazole–octanedioic acid (2/1)
Cocrystallization of 2-amino-6-methy-1,3-benzothia-zole with octa-nedioic acid in a mixed methanol-water medium afforded the title 2:1 cocrystal, 2C(8)H(8)N(2)S·C(8)H(14)O(4). The octa-nedioic acid mol-ecule is located on an inversion centre. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds connect the components into a three-dimensional network.
