CC48 reduces tumor cells proliferation in treated mice (A) Histological sections stained with hematoxylin & eosin, representative of the tumor masses from each of the three experimental groups, vehicle-treated control group (GP1), group treated with 10 mg/Kg CC48 (GP2) and group treated with 20 mg/Kg CC48 (GP3) Lens: 10X. Bar: 100 μm. Circled areas enclose details of each histologic section taken at 40X magnification. In GP1 there are viable neoplastic cells, in GP2 the red arrow on the left indicates the necrotic area, and the two red arrows on the right indicate the lymphocytic infiltrate. In the GP3 group of mice, where the malignancy infiltrates the striated muscle of the murine diaphragm, the left arrow indicates a foamy histiocyte with fragmented nucleus, the right arrow indicates another foamy histiocyte with pyknotic nucleus (hydropic degeneration of tumor tissue) Lens: 40X. Bar: 25 μm. (B) At Immunohistochemical analysis of the intra-tumoral Ki67 marker as an index of cell proliferation, we calculated a mean of 35% of Ki67 stained nuclei in GP1 and a mean of 15–20% in GP2/GP3 (* p < 0.05 GP3 vs. GP1). Red arrows indicate some Ki67 positive nuclei. Lens: 10X. Bar: 100 μm. (C) The sampled tumor masses were photographed on graph paper. Images are representative of each treatment group

CB2R agonist CC48 reduces circulating levels of specific inflammatory cytokine. Serum levels of eotaxin, G-CSF, IFN-γ, IL-1α, IL-12 (p70), IL-17 A, GRO/KC (CXCL1), MCP-1 (CCL2), MIP-1β and RANTES were measured in serum samples and compared within the three experimental groups (GP1: vehicle; GP2: 10 mg/Kg CC48; GP3: 20 mg/Kg CC48). For each analyte, the value is the average of the six mice in each group ± SD ed expressed as pg/mL.* p < 0.05; ** p < 0.01

Effects of CC48 on tumour growth, selected as a first-in-class cannabinoid receptor type 2 (CB2R) multi-target agent. The agonist CC48 exerts its antitumour activity in gastric cancer cell models by (i) binding to CB2R; (ii) inhibiting the FAAH enzyme; (iii) interacting with the P-gp protein responsible for the efflux of the chemotherapeutic drug PTX from the tumor cell. The main molecular pathways regulated by CC48 and involved in proliferation, autophagy and apoptosis were depicted. Previous studies have shown that the same pathways are involved in the anti-tumor activity of PTX. CC48 enhances PTX-induced cell growth inhibition, even in chemotherapy-resistant cell models.
