Spirooxindole derivative SOID-8 induces apoptosis associated with inhibition of JAK2/STAT3 signaling in melanoma cells. [PDF]

PLoS ONE, 2012
Melanoma is generally refractory to current chemotherapy, thus new treatment strategies are needed. In this study, we synthesized a series of spirooxindole derivatives (SOID-1 to SOID-12) and evaluated their antitumor effects on melanoma.

From data to discovery: leveraging big data in plant natural products biosynthesis research. [PDF]

Plant J
SUMMARY Plant natural products or specialized metabolites play a vital role in drug discovery and development, with many clinically important derivatives such as the anticancer drugs topotecan (derived from the natural alkaloid camptothecin) and etoposide (derived from the natural polyphenol podophyllotoxin).

Discovery of spirooxindole-derived small-molecule compounds as novel HDAC/MDM2 dual inhibitors and investigation of their anticancer activity

Frontiers in Oncology, 2022
Simultaneous inhibition of more than one target is considered to be a novel strategy in cancer therapy. Owing to the importance of histone deacetylases (HDACs) and p53-murine double minute 2 (MDM2) interaction in tumor development and their synergistic ...

In Vitro and In Silico Evaluation of Isatin‐Derived Spirooxindoles as Antituberculosis Drug Candidates

Chemical Biology &Drug Design, Volume 106, Issue 1, July 2025.
Two compounds, A16 and A17, were active against multidrug‐resistant Mycobacterium tuberculosis isolates (PT‐12 and PT‐20), overcoming key resistance mutations in katG and rpoB, while cytotoxicity assays confirmed that they are non‐toxic. A17 exhibited the highest antituberculosis activity, with molecular docking suggesting enoyl‐[acyl‐carrier‐protein ...

Diastereoselective Three-Component 1,3-Dipolar Cycloaddition to Access Functionalized β-Tetrahydrocarboline- and Tetrahydroisoquinoline-Fused Spirooxindoles [PDF]

Molecules
A chemselective catalyst-free three-component 1,3-dipolar cycloaddition has been described. The unique polycyclic THPI and THIQs were creatively employed as dipolarophiles, which led to the formation of functionalized β-tetrahydrocarboline- and ...
