Dr.Su's research focuses on anti-cancer and anti-trypanosome drug development

1. Hsp27 inhibitor development. The expression of heat shock proteins (Hsp) is increased under lethal conditions, which is a typical response when cancer cells are stressed by chemotherapies. Hsp27, a small heat shock protein, shows a very tight correlation with anti-cancer drug resistance. Its over-expression enhances the survival of mammalian cells exposed to anti-cancer agents. Through biotinylated small molecular probe, affinity chromatography and proteomic approaches, our lab identified small molecule compound binding to Hsp27. Systematic ligand based optimization dramatically increased the cell proliferation inhibition and apoptosis inducing activities of the compounds. Drug candidates developed in this project have been tested by the Developmental Therapeutic Program at the National Cancer Institute for screening against 60 human cancer cell lines, representing leukemia, melanoma, and cancers of the lung, colon, CNS, ovary, renal, prostate, and breast. Our lab currently further optimizes the drug candidates to improve the ADME profile.

2. Selective tubulin inhibitors for the treatment of African trypanosomiasis. By collaborating with Dr. Bibo Li at BGES, we screened the small molecule compound library generated in our lab with T.brucei which is the parasite causing African sleep disease. Interestingly, we identified several lead compounds that selectively inhibited the parasite growth, and did not affect the mammalian cell proliferation. These compounds selectively interfere with parasite tubulin, and do not block the mammalian tubulin function. There is a great potential to develop cheap, easy make drug candidates for the treatment of the parasite disease.  

3. Lead optimization of HMBA, a cell differentiation agent. Hexamethylene bisacetamide (HMBA) is an agent showing promising anti-cancer activities. It has been investigated at national cancer institute in phase II clinical trial for cancer treatment. However, the dose related toxicity limited the further drug development. The compound exhibited its anti-cancer activity at micro mole range in the in vitro assays. It is critical to develop more potent analogs which will show lower toxicity. Dr. Monica Montano at CWRU pharmacology collaborates with us to optimize this compound. So far, about 40 new analogs have been developed. Very fortunately, we identified one derivative is 2500 times more active than the parental HMBA. We focus on the molecular targets identification of HMBA and its analogs currently
