Concanamycin A is a specific inhibitor of vacuolar-type ATPase (V-ATPase) with IC50 value of 10 nM [1].
Vacuolar-type ATPase (V-ATPase) is expressed by clear cells to acidify the lumen of the epididymis, which is essential for male fertility; what's more, it induced proton extrusion into the extracellular medium which contributes to maintaining the intracellular pH under an acidic microenvironment. V-ATPase has also been reported to involve in the process of acidificating microenvironment around/in solid tumors and inducing tumor invasion/multi-drug resistance in several malignant tumors. [2].
Concanamycin A (CMA) is a specific V-ATPase inhibitor and is different from the reported V-ATPase inhibitor SS33410. In oral squamous cell carcinoma (OSCC) OSCC cell lines (MISK81-5, SAS and HSC-4), low-concentration of CMA treatment induced the apoptosis of tumor cells [3]. Pretreated colorectal cancer cell lines with concanamycin A could significantly enhanced the Tumour necrosis factor (TNF) related apoptosis inducing ligand (TRAIL)-induced apoptosis by blocking endosomal acidification by V-ATPase [4]. When tested with prostate cancer cell line C4-2B, inhibition of V-ATPase by concanamycin A reduced 80% invasion in vitro [5].
Concanamycin A also had been reported as a potent inhibitor of CTL cytotoxicity via perforin-mediated cytotoxic pathway [6].

|
Cell lines |
HCT-116, DLD-1, Colo206F, HeLa cells, Androgen-dependent (LNCaP) and androgen-independent (C4-2B) cells. |
|
Preparation method |
This compound is limited soluble in DMSO. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |

Reacting condition |

|
Applications |
CCA effectively attenuated the TRAIL-induced activation of caspases in TRAIL-sensitive colorectal cancer cell lines. In CCA-treated Colo206F cells, the number of M30-positive apoptotic cells gradually increased and almost reached the proportion seen in untreated cells within 3–4h after the addition of TRAIL. Treatment with CCA resulted in a lack of apoptosis-related chromatin condensation in DLD-1 cells incubated with TRAIL for 90 min. Treatment with nanomolar concentrations of concanamycin A reduced the in vitro invasion in LNCaP and C4-2B cell types by 80%. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
