Oxindole

Research use only, not for human use.

Oxindole is an aromatic heterocyclic building block. 2-indolinone derivatives have become lead compounds in the research of kinase inhibitors.Oxindole structure has been used in receptor tyrosine kinases (RTKs) inhibitors such as SU4984 and intedanib, the RTK family represents an important therapeutic target for anti-cancer drug development.

METHODS AND RESULTS: The synthesis started from 5-chloroOxindole, which was condensed with methyl 4-carboxybezoate and result in the formation of benzolyester derivatives of Oxindole which was then treated with hydrazine hydrate. The Oxindole benzoylhydrazide was treated with aryl acetophenones and aldehydes to get target compounds 5-24. The synthesized compounds were evaluated for urease inhibition; the compound 5 (IC50 = 13.00 ± 0.35 μM) and 11 (IC50 = 19.20 ± 0.50 μM) showed potent activity as compared to the standard drug thiourea (IC50 = 21.00 ± 0.01 μM). Other compounds showed moderate to weak activity.

Oxindole (Indolin-2-one) is a bicyclic structure consisting of a benzene ring fused to 2-pyrrolidone. Substituted indolinones can be referred as ‘privileged structures’ owing to their excellent binding affinity for many receptors and to the number of approved drugs containing this scaffold. Oxindole has been found in tissues and fluids of mammals as well as natural products produced by a range of plants, bacteria and invertebrates. 2-indolinone derivatives possess diverse range of pharmacological activities including anti-cancer, anti-HIV, anti-diabetic, antibacterial, antioxidant, kinase inhibitory, AChE inhibitory, anti-leishmanial, b3 adrenergic receptor agonistic, phosphatase inhibitory, analgesic, spermicidal, vasopressin antagonists, progesterone antagonists, neuroprotection, NMDA blocker and sleep inducing activities.
