Background

Chloropyramine hydrochloride (Halopyramine) is a histamine receptor H1 antagonist and has anti-cholinergic, antispasmodic, and antiallergic effects.

Protocol

Kinase experiment:	Cells are incubated in presence or absence of Chloropyramine hydrochloride and stained with anti-FAK antibody 4.47 or in combination with paxillin or VEGFR-3. Detection is done with Alexa Fluor 546 secondary antibody and for dual staining combination of Alexa Fluor 488 and Alexa Fluor 546 secondary antibody is used[1].
Cell experiment:	Cell survival is assayed in MTS assay by measuring mitochondrial dehydrogenase activity of metabolically active cells. 5.0×103 (100 μL) cells are plated in 96-well plates and are allowed to attach overnight. One hundred microliters of fresh media with or without Chloropyramine hydrochloride is added to each well. Cells are treated for designated amount of time. MTS assay is performed according the manufacturers protocol[1].
Animal experiment:	BT474 and MCF7-VEGFR-3 cells at a concentration of 2 to 5×106 cells per 200 μL are subcutaneously injected into the right flank of the 5 to 6 week old mice, 5 in each group. Treatment with Chloropyramine hydrochloride is started next day after cells injection via intraperitoneal injection (IP) once a day. Tumor size is measured thrice weekly and volume is calculated using the formula length×width2×0.5. Animals are sacrificed after 21 days of treatment or when tumor size reaches protocol end point. Tumor is excised, measured and preserved for protein and RNA preparation and cytochemistry[1].
