Insufficient transport of therapeutic cargo into tumor bed is a bottleneck in cancer nanomedicine. Block copolymers are promising carriers with smaller particle size by ratio modification. Here, we constructed cisplatin nanoparticles with sizes ranging from 8 to 40 nm to study the permeability and therapy of Lewis lung carcinoma. We synthesized methoxypoly(ethylene glycol)2000-block poly(L-glutamic acid sodium salt)1979 loading cisplatin through complexation reaction. The cisplatin nanomedicine has high drug loading and encapsulation efficiency. In vitro data demonstrated that cisplatin nanoparticles had equivalent growth-inhibiting effects on Lewis lung carcinoma cells compared to free cisplatin. In vivo evidences showed cisplatin nanoparticles had superior antitumor effects on the Lewis lung carcinoma mouse model with no obvious side effects. All results indicated that optimizing the ratio of block copolymers to obtain smaller sized nanomedicine could act as a promising strategy for overcoming the inadequate accumulation in poorly vascularized tumors.

Although L-Asparaginase (L-ASP) is an effective chemotherapeutic agent, it has side effects such as fever, skin rashes, chills, anaphylaxis, and severe allergic reactions. Moreover, the short half-life of L-ASP reduces its antitumor activity. To reduce its side effects and broaden its pharmaceutical applications, L-ASP obtained from Pectobacterium carotovorum was subjected to liposomal conjugation. The enzyme was then loaded into liposomes using the hydrated thin-film method. The in vitro cytotoxic activity of liposomal L-ASP was evaluated with the MTT assay using cancerous cell lines, and its antitumor effects were examined in Lewis lung carcinoma (LLC) tumorized mice. The average size of the liposomes containing purified L-asparagine was 93.03 ± 0.49 nm. They had a zeta potential of –15.45 ± 6.72 mV, polydispersity index of 0.22 ± 0.02, and encapsulation efficiency of 53.99 ± 5.44%. The in vitro cytotoxic activity of liposomal L-ASP was less effective against LLC, MCF-7 (human breast carcinoma), HepG2 (human hepatocellular carcinoma), SK-LU-1 (human lung carcinoma), and NTERA-2 (pluripotent human embryonic carcinoma) cells than that of free L-ASP. However, the antitumor activity of liposomal L-ASP was significantly greater than that of untrapped L-ASP at the same doses (6 UI/mouse) in terms of tumor size (6309.11 ± 414.06 mm3) and life span (35.00 ± 1.12 days). This is the first time the antitumor activities of PEGylated nanoliposomal L-ASP have been assessed in LLC carcinoma tumor-induced BALB/c mice and showed significantly improved pharmacological properties compared to those of free L-ASP (P<0.05). Thus, nanoliposomal L-ASP should be considered for its widening applications against carcinoma tumors.
