BCTC is a selective and orally bioactive vanilloid receptor 1 (TRPV1 receptor) antagonist. Inhibits acid- and capsaicin-induced activation of rat TRPV1 receptors (IC50 are 6.0 and 35 nM respectively). BCTC significantly reduced the accompanying thermal and mechanical hyperalgesia (3 mg/kg and 10 mg/kg p.o., respectively). BCTC also reduced mechanical hyperalgesia and tactile allodynia 2 weeks after partial sciatic nerve injury (10 and 30 mg/kg p.o.). BCTC did not affect motor performance on the rotarod after administration of doses up to 50 mg/kg p.o.

Biological Activity
| ln Vitro | On DU145 cells, BCTC (20-100 μM; 72 h) exhibits very specific anti-tumor action [1]. By selectively controlling the expression levels of a handful of cell cycle regulatory proteins, BCTC (20-100 μM; 48 h) produces cell cycle arrest in the G0/G1 phase without inducing apoptosis (10 μM and 100 μM; 72 h). Demise [1]. Cell migration and invasion are inhibited by BCTC (10μM and 100μM; 48 h) [1]. Rat spinal cord TRPV1 function is effectively inhibited by BCTC (3-300 nM), which also reduces capsaicin (300 nM)-induced calcitonin gene-related peptide-like immunoreactivity (CGRP-LI) (IC50=37.0 nM) and p-like substance immunoreactivity in rat spinal cord slices (SP-LI) (IC50=36.0 nM) [3]. |
| ln Vivo | By targeting VR1, BCTC (1-30 mg/kg; oral administration; single dosage) has analgesic effects and can reduce neuropathic and inflammatory thermal allodynia as well as mechanical hyperalgesia in Sprague-Dawley rats[2]. In diabetic ob/ob mice, BCTC (10–100 mg/kg; oral dosing, twice daily for 4 weeks) can enhance insulin production and improve systemic glucose and lipid metabolism as well as insulin resistance [5]. |
| Cell Assay |
Western Blot Analysis[1] Cell Types: DU145 Tested Concentrations: 20 μM, 40 μM, 60 μM, 80 μM, 100 μM Incubation Duration: 48 h Experimental Results: Down-regulates p-Akt, while p-GSK-3β is up-regulated leaving their unphosphorylated form unchanged. Dramatically down-regulated Cyclin D1(20), the most relevant protein in the cell cycle, without affecting cyclin-B1. decreased the expression of CDK2 and CDK6, but without affecting the expression level of CDK4. Downregulates MMP2 and p-FAK levels. Cell Viability Assay[1] Cell Types: DU145, PNT1A Tested Concentrations: 20 μM, 40 μM, 60 μM, 80 μM, 100 μM Incubation Duration: 72 h Experimental Results: diminished the growth of DU145 cells in a concentration -dependent manner, with 12.03% and 50.69% growth inhibition at 10 µM and 100 µM, respectively, but had little effect on normal prostate PNT1A cells. |

Animal/Disease Models: Capsaicin-induced SD (Sprague-Dawley) rats model[2] Doses: 1 mg/kg, 3 mg/kg, 10 mg/kg, 30 mg/kg Route of Administration: po (oral gavage), Single dose. Before capsaicin treatment ( 30 μg; intraplantar injection; Single dose) Experimental Results: Inhibited capsaicin-mediated thermal hyperalgesia in a dose-dependent manner.
