The crystal and molecular structure of (1-n-butyl-2,6,6'-trimethyl-4-oxo - 4,5,6,7 - tetrahydro - 3 indole acetic acid) with desirable anti hyperglycemic properties is reported. The title compound crystallises in orthorhombic space group Pbca with z =8. The unit cell dimensions are a=15.698(13)A, b= 11.639(2)A, c = 18.506(3)A, V =3381.2(29)A3, Dcal = 1.145Mg/m3. The cyclohexane ring adopts a sofa conformation. The structure is stabilized by C-H---O and O-H---O hydrogen bonds. Molecular modeling studies on this class of compounds and the classical antidiabetic agent tolbutamide reveal a structural basis for the similar biological activity exhibited by two totally structurally unrelated compounds.
Synthesis and oral hypoglycemic properties of two 4-oxo-4,5,6,7-tetrahydroindole-3-acetic acids

, p. 548 - 550 (2007/10/02)
Condensation of β-acetyl-2-hydroxy-4,4-dimethyl-6-oxo-1- cyclohexene-1-propionic acid (3) with n-butyl and isobutylamines affords the title acids 4 and 5, respectively, which show good oral hypoglycemic activity in normal rats. Acids 4 and 5, are also active in streptozocin-induced diabetic rats. Results of extensive pharmacological and acute toxicity tests are reported.

Condensation of β-acetyl-2-hydroxy-4,4-dimethyl-6-oxo-1-cyclohexene-1-propionic acid (8, R =R1 =Me) with ammonium acetate and primary amines affords tetrahydroindole-3-acetic acids (9), while another dimedone derivative 13 serves as starting material for isomeric indole-2-acetic acids (15). 4-Oxotetrahydroindole-2-carboxylic acids (77, 78) and 3-carboxylic acids (85, 86) are obtained from the corresponding benzofurans.Some of the 3-carboxylic acid esters are transformed to tricyclic compounds like 21-25.Good oral hypoglycemic activity in normal rats is shown generally by the 3-acetic acids among which C 8778-GO (3) and C 9001-GO (4) are most active.These two acids are also active in streptozotocin-induced diabetic rats and have been investigated extensively.Structure-activity relationships are discussed.
