|Synthesis of novel derivatives of oxindole, their urease inhibition and molecular docking studies.[Pubmed: 26077497]|
|We synthesized a series of novel 5-24 derivatives of Oxindole.
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.
All synthetic compounds were characterized by different spectroscopic techniques including (1)H NMR, (13)C NMR, IR and EI MS.The molecular interactions of the active compounds within the binding site of urease enzyme were studied through molecular docking simulations.

||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: email@example.com
||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

|Synthesis and biological evaluation of novel oxindole-based RTK inhibitors as anti-cancer agents.[Pubmed: 25456085]|
|Given that receptor tyrosine kinases (RTKs) have emerged as key regulators of all aspects of cancer development, including proliferation, invasion, angiogenesis and metastasis, the RTK family represents an important therapeutic target for anti-cancer drug development. Oxindole structure has been used in RTK inhibitors such as SU4984 and intedanib.
METHODS AND RESULTS:
In this study, two series of new heterocyclic compounds containing Oxindole scaffold have been designed and synthesized, and their inhibitory activity against the proliferation of nine cancer cell lines has been evaluated. Among them, compounds 9a and 9b displayed the strongest anti-proliferative activity with the IC50s below 10μM. Flow cytometric analysis showed that the compounds 9a and 9b dose-dependently arrested the cell cycle at G0/G1 phase. Although the leading compounds SU4984 and intedanib targets FGFR1, the kinase activity test revealed that these compounds only showed slight inhibitory activity on FGFR1 kinase.
Further enzymatic test aided by molecular docking simulation in the ATP-binding site demonstrated that 9a and 9b are potent inhibitors of c-Kit kinase. These compounds are worthy of further evaluation as anticancer agents.
