Tumor secreted substances (secretome), including extracellular matrix (ECM) components, act as mediators of tumor-host communication in the breast tumor microenvironment. Proteomic analysis has emphasized the value of the secretome as a source of prospective markers and drug targets for the treatment of breast cancers. Utilizing bioinformatics, our recent(More)
This report describes the synthesis of four novel paclitaxel based prodrugs with glycan conjugation (1-4). Glycans were conjugated using an ester or ether bond as the linker between 2'-paclitaxel and the 2'-glucose or glucuronic acid moiety. These prodrugs showed good water solubility and selective cytotoxicity against cancer cell lines, but showed reduced(More)
Bisphosphonates can mimic the pyrophosphate leaving group of the nucleotidyl transfer reaction and effectively inhibit RNA/DNA polymerases. In a search of HIV-1 reverse transcriptase (RT) inhibitors, a new chemotype of nonhydrolyzable purine diphosphate mimic was synthesized. A modular synthetic protocol was developed, utilizing(More)
Human farnesyl pyrophosphate synthase (FPPS) controls intracellular levels of farnesyl pyrophosphate, which is essential for various biological processes. Bisphosphonate inhibitors of human FPPS are valuable therapeutics for the treatment of bone-resorption disorders and have also demonstrated efficacy in multiple tumor types. Inhibition of human FPPS by(More)
Nitrogen-containing bisphosphonates (N-BPs) are potent active site inhibitors of the human farnesyl pyrophosphate synthase (hFPPS) and valuable human therapeutics for the treatment of bone-related malignancies. N-BPs are also useful in combination chemotherapy for patients with breast, prostate and multiple myeloma cancers. A structure-based approach was(More)
Human farnesyl pyrophosphate synthase (hFPPS) produces farnesyl pyrophosphate, an isoprenoid essential for a variety of cellular processes. The enzyme has been well established as the molecular target of the nitrogen-containing bisphosphonates (N-BPs), which are best known for their antiresorptive effects in bone but are also known for their anticancer(More)
Human farnesyl pyrophosphate synthase (hFPPS) is the gate-keeper of mammalian isoprenoids and the key target of bisphosphonate drugs. Bisphosphonates suffer from poor "drug-like" properties and are mainly effective in treating skeletal diseases. Recent investigations have implicated hFPPS in various nonskeletal diseases, including Alzheimer's disease (AD).(More)
In order to explore the interactions of bisphosphonate ligands with the active site and an allosteric pocket of the human farnesyl pyrophosphate synthase (hFPPS), substituted indole and azabenzimidazole bisphosphonates were designed as chameleon ligands. NMR and crystallographic studies revealed that these compounds can occupy both sub-pockets of the active(More)
Aurora kinases have emerged as important anticancer targets so that there are several inhibitors have advanced into clinical study. Herein, we identified novel indazole derivatives as potent Aurora kinases inhibitors by utilizing in silico fragment-based approach and knowledge-based drug design. After intensive hit-to-lead optimization, compounds 17 (dual(More)
Human farnesyl pyrophosphate synthase (hFPPS) controls intracellular levels of FPP and post-translational prenylation of small GTPase proteins, which are essential for cell signaling and cell proliferation. Clinical investigations provide evidence that N-BP inhibitors of hFPPS are disease modifying agents that improve survival of multiple myeloma (MM)(More)
