Design of small-molecule CXCR4 antagonists for HIV and cancer treatment:

CXCR4 is a G-protein coupled receptor for the chemokine CXCL12 (SDF-1), which is involved in cell migration and proliferation. It is also a co-receptor used by the X4 strains of HIV, which predominate at later stages of infection, and is required for their entry into target cells. We are designing and synthesizing non-peptide small molecule inhibitors of CXCR4 based on modeling studies. Lead compounds that compete with known CXCR4 antagonists, such as the peptide T-140, are being investigated for their ability to inhibit HIV infection in vitro, and to inhibit tumor cell metastasis in vitro and in a mouse model.


Development of broad-spectrum antibacterial compounds:

Compounds with multiple biguanide groups such as chlorhexidine, alexidine, and PHMB are used as topical antimicrobials in a variety of settings. We have synthesized a series of small molecules with guanide, biguanide, and arylguanide functional groups that have comparable broad spectrum antibacterial activity, but lower cytotoxicity towards mammalian cells. We are investigating their mechanism of action and further optimizing their structures.
