Description of Mastoparan

Mastoparan, a peptide toxin from wasp venom, induces stimulation of phosphoinositide breakdown with an EC50 value of 9μM[1]. Mastoparan accelerates guanosine-5'-3-O-thiotriphosphate binding and consequent GTP-binding regulatory protein (G protein) activation in part by enhancing the dissociation of bound GDP[2]. Mastoparan has been widely used in anti-inflammatory studies and as a model compound to develop related derivatives[3].

In vitro, Mastoparan exhibited an anticancer towards Hep-G2 cells with IC50=189.59±0.6µg/ml after 24h treatment[4]. Treatment with 25μM Mastoparan for 8h significantly induced cell death in Jurkat T leukemia cells and normal peripheral blood cells[5]. Mastoparan treatment at 20μM within 1min significantly induced a rapid increase in cytosolic-free Ca2+ concentration elevation in Tobacco BY-2 cells[6].

In vivo, Mastoparan treatment via a peritumor route at 5 mg/kg/day for 5 consecutive days inhibited the tumor growth in the murine melanoma model[7]. The combination therapy of gemcitabine (60mg/kg/day) and Mastoparan (6mg/kg/day) for 14 days via intraperitoneal injection significantly inhibited tumor progression in a mouse model of breast cancer[5].

Protocol of Mastoparan

Cell experiment [1]:

Cell lines

Immortalized human dermal microvessel endothelial cells

Preparation Method

The growth of immortalized human dermal microvessel endothelial cells (HMECs) occurred in MCDB-131 medium which contained 10% inactivated FBS and 2mM glutamine as well as 100U/ml penicillin and 100μg/ml streptomycin. HMECs were seeded in 24-well culture plates (approximate cell density, 3×105 cells/well) containing medium supplemented with 5% heat-inactivated FBS. After cells reached confluence, cells were stimulated for 6h with lipopolysaccharide (LPS) at 10ng/ml, with or without a 30min preincubation of cells with Mastoparan (0, 5, 10, 15, 20, and 25μM). Supernatants were harvested and assayed for IL-6 activity by ELISA.

Reaction Conditions

0, 5, 10, 15, 20, and 25μM; 30min

Applications

Mastoparan exerted a dose-dependent inhibition on the expression and secretion of IL-6 induced by LPS.
Animal experiment [2]:

Animal models

C57BL/6 mice

Preparation Method

At 6 to 8 weeks of age of male C57BL/6 mice, 5×104 viable B16F10-Nex2 cells were subcutaneously (s.c.) inoculated on the right side of male C57BL/6 mice. When the tumor reached a volume of 100mm3, the mice received 5 weekly intratumoral doses of Mastoparan (5mg/kg/day). The untreated tumor control group received 100μL PBS. After administration of the therapeutic dose, the tumor size was measured daily using a caliper. The tumor volume (V) was calculated using the formula V=0.52×d2×D, where d and D are the short and long diameters of the tumor, respectively. When the tumor size reached a maximum of 3000mm3, the animals were sacrificed for subsequent experimental analysis.

Dosage form

5mg/kg/day for 5 weeks a day; i.t.

Applications

Mastoparan treatment inhibited the growth of subcutaneous melanoma in mice and increased the survival rate.
