BACKGROUND Pirarubicin, a derivative of doxorubicin, induces tumor destruction via the production of reactive oxygen species (ROS) but is associated with cardiotoxicity. As a macromolecule (conjugated to styrene-maleic acid [SMA]), SMA-pirarubicin is selective to tumors resulting in improved

pH-responsive polymers render liposomes pH-sensitive and facilitate the intracellular release of encapsulated payload by fusing with endovascular membranes under mildly acidic conditions found inside cellular endosomes. The present study reports the use of high-molecular weight

Patients with triple negative breast cancer have a poor prognosis due in part to the lack of targeted therapies. In the search for novel drugs, our laboratory has developed a second-generation curcumin derivative, 3,5-bis(3,4,5-trimethoxybenzylidene)-1-methylpiperidine-4-one (RL71), that exhibits

The purpose of this study was to design a targeted anti-cancer drug delivery system for breast cancer. Therefore, doxorubicin (DOX) loaded poly(methyl vinyl ether maleic acid) nanoparticles (NPs) were prepared by ionic cross-linking method using Zn(2+) ions. To optimise the effect of DOX/polymer

To assess the characteristics of a zinostatin derivative, 29 patients with multiple hepatocellular carcinoma of 3 cm or less in diameter were treated with intra-arterial injection of the high molecular weight anti-tumor agent, styrene-maleic acid neocarzinostatin, mixed with Lipiodol. Computerized

To assess the efficacy of the zinostatin derivative, the anti-tumor agent, styrene-maleic acid neocarzinostatin, in treating multiple small liver cancers, 29 patients with multiple hepatocellular carcinoma of 3 cm or less in diameter were treated with intraarterial injections of this high molecular

Previous studies indicated the potential of styrene maleic acid copolymer (SMA)-conjugated pirarubicin (4'-O-tetrahydropyranyldoxorubicin [THP]) for targeted anticancer therapy based on the enhanced permeability and retention effect. In this study, to achieve further improved therapeutic efficacy, a

The development of non-specific resistance to tumors following stimulation with poly(maleic-acid-styrene)-conjugated neocarzinostatin (SMANCS), a polymer-conjugated derivative of neocarzinostatin, was investigated in mice. The growth of syngeneic solid tumors (Meth-A fibrosarcoma and RL male 1

Cisplatin (CDDP) is widely used to treat various cancers. However, its distribution to normal tissues causes serious adverse effects. For this study, we synthesized a complex of styrene-maleic acid copolymer (SMA) and CDDP (SMA-CDDP), which formed polymeric micelles, to achieve tumor-selective drug

Although increasing evidence have confirmed that carbon monoxide release molecule-2(CORM-2) plays an active role in the treatment of inflammation and tumors, poor aqueous solubility and short CO-release duration restrict its extensive application. Our previous work synthesized styrene-maleic acid

We have previously shown that the curcumin derivative 3,5-bis(3,4,5-trimethoxybenzylidene)-1-methylpiperidine-4-one (RL71), when encapsulated in styrene maleic acid micelles (SMA-RL71), significantly suppressed the growth of MDA-MB-231 xenografts by 67%. Univariate statistical analysis showed that

A 54 year-old man was admitted to our hospital and diagnosed with inoperable cancer in the body and tail of the pancreas. The spleen was embolized at its hilum with a coil to infuse an anti-tumor agent selectively into the pancreatic parenchyma and transcatheter intraarterial infusion (TAI) of

In the present study, we have synthesized poly(styrene-co-maleic anhydride), a biocompatible copolymer that was further conjugated with paclitaxel (PTX) via ester linkage and self-assembled to form poly(styrene-co-maleic acid)-paclitaxel (PSMAC-PTX) nanoparticles (NPs). The in vitro release of PTX

Purpose Raloxifene (RA) receptors have over-expressed GPER-positive breast cancer tumors. The purpose of this work was to evaluate the antitumor activity and pharmacokinetic behavior of docetaxel (DTX), loaded in RA-targeted nanomicelles, which were designed to overcome a lack of specific
