Clinical Trials

Several clinical trials are evaluating therapeutic interventions across neurodegenerative, psychiatric, and cerebrovascular conditions, specifically targeting Parkinson's disease, major and persistent depressive disorders, and stroke. Ranging from Phase 1 and Phase 2 protocols to studies categorized as Not Applicable, all entries are currently in a not yet recruiting status. Sponsored by entities including the VA Office of Research and Development, the University of Pennsylvania in conjunction with the National Institutes of Health, and UMC Utrecht, these investigations focus on neuroplasticity, subgenual cingulate stimulation, and post-stroke motor recovery.

Compliance for Clinical Use

Mechanism and Biochemical Profile

TMS ((E)-2,3',4,5'-tetramethoxystilbene) acts as a potent, selective, and competitive human cytochrome P450 1B1 (CYP1B1) inhibitor with an IC50 of 6 nM, effectively blocking CYP1B1-mediated metabolic activation of endogenous and exogenous substrates. By preventing downstream procarcinogen bioactivation and cellular oxidative stress, this target inhibition provides potential clinical relevance for modulating neuroinflammatory and metabolic pathomechanisms studied in clinical trials for Parkinson's disease, depression, and stroke.

Appendix RUO and cGMP Quality Standards

Quality Dimension RUO (Research Use Only) cGMP (Current Good Manufacturing Practice)
Clinical Applicability Prohibited in human clinical trials or medical diagnostics. Mandatory for human clinical trials (Phase I–III) and therapies.
Regulatory Status Non-regulated grade; exempt from drug manufacturing laws. Legally enforced by health authorities (e.g., FDA, EMA, NMPA).
Facility Environment Unclassified analytical or research laboratories. Validated Cleanrooms (ISO Class 5–8) with continuous monitoring.
Quality Control Basic purity and activity testing. Rigorous safety release testing (Sterility, Endotoxin, Mycoplasma).
Process Validation Basic equipment calibration; no process validation required. Full qualification (IQ/OQ/PQ) and complete batch records.
Quality Assurance Vendor self-declared without required formal QMS. Mandatory QA/QC unit, Change Control, CAPA, and vendor audits.
Regulatory Impact High risk of IND rejection if used as a critical raw material. Required for IND/NDA filings, supported by Drug Master Files (DMF).
