More recently, a pegylated (PEG) zinc protoporphyrin (PEG-ZnPP) and a highly water soluble micellar formulation of ZnPP based on amphiphilic styrene maleic acid (SMA) copolymer, SMA-ZnPP, are prepared, which are potent inhibitors of heme oxygenase-1 (HO-1).

Such therapeutic strategies are described in this article, that includes polymeric superoxide dismutase (SOD) (e.g., pyran copolymer-SOD), xanthine oxidase (XO) inhibitor as we developed water soluble form of 4-amino-6-hydroxypyrazolo [3,4-d] pyrimidine (AHPP), heme oxygenase-1 (HO-1) inducers (e.g., hemin and its polymeric form), and other antioxidants or radical scavengers (e.g., canolol).

The micellar macromolecular drug of ZnPP (SMA-ZnPP and PEG-ZnPP) previously showed notable anticancer activity as a consequence of selective tumor targeting ability and its potent HO-1 inhibitory potential, resulting in suppressed biliverdin/bilirubin production in tumors thereby leading to oxystress induced tumor cell killing.

The gene expressions of collagen-I, transforming growth factor-beta1 (TGF-beta1), tissue inhibitor of metalloproteinases-1 (TIMP-1), interleukin-6 (IL-6) and heme oxygenase-1 (HO-1) in the liver were examined by real-time reverse transcriptase polymerase chain reaction (RT-PCR).

Curr Cancer Drug Targets. 2009 Aug;9(5):675-89. Epub 2009 Aug 1.


Heat shock protein 32 (Hsp32), also known as heme oxygenase-1 (HO-1), is a stress-related anti-apoptotic molecule, that has been implicated in enhanced survival of neoplastic cells and in drug-resistance.

In vivo studies showed that the hepatic levels of collagen, malondialdehyde, TNF-alpha, IL-6, and IL-1beta, fibrosis scores and protein expressions of alpha-SMA, heme-oxygenase-1, iNOS, and gp91 (phox), and serum levels of ALT, AST, IL-6, and IL-1beta were increased in TAA-intoxicated rats, all of which were attenuated by 4-week treatment of Sal A or Sal B.

Protein expression levels of the pro-inflammatory cytokine, TNF-alpha, the pro-fibrotic transcription factor, NFkappaB, a measure of oxidative stress (heme oxygenase-1), alpha-SMA, vimentin and TGFss1 were determined.
