We previously reported interim results of a phase 1 trial in patients with chronic lymphocytic leukemia (CLL) whereby flavopiridol was administered intravenously as a 30-minute bolus followed by 4-hour infusion. We now report full pharmacokinetic (PK) data, correlations of PK with clinical outcomes, and final response and progression-free survival (PFS). Twenty-one (40%) of 52 patients with rel...
Treatment of the human colon cancer cells Hct116 with SN-38 (an active metabolite of CPT-11) resulted in G2 cell cycle arrest without induction of apoptosis. However, subsequent treatment of SN-38-treated Hct116 cells with flavopiridol induced apoptosis. One of the genes markedly up-regulated during cell cycle arrest by SN-38 and suppressed during apoptosis by SN-38 followed by flavopiridol in ...
Spheroids have been shown to recapitulate the tumour in vivo with properties such as the tumour microenvironment, concentration gradients, and tumour phenotype. As such, it can serve as a platform for determining the growth and invasion behaviour pattern of the cancer cells as well as be utilised for drug sensitivity assays; capable of exhibiting results that are closer to what is observed in v...
Cancer chemotherapeutic drugs acts in different manner to kill malignant cells. Most of the anticancer available clinical practice treat cancer patients, are natural products including whole plant extract, crude extracts, isolated constituents, –based drug formulations etc. These compounds have been a basis for development several against cancer. Agents such as topotecan, taxol, vinca alkaloids...
The fraction of noncycling cells found in most tumors represents a major obstacle for conventional chemotherapy. Here, we show that the cyclin-dependent kinase inhibitor p27KIP-1 accumulates to high levels in human tumors grown in immunodeficient mice. We have developed an antisense phosphorothioate oligodeoxynucleotide (ODN) that efficiently inhibits the expression of p27KIP-1 both in vitro an...
BACKGROUND: Many potential new antineoplastic agents are currently in various stages of clinical development. Three areas of drug development include antiangiogenic compounds, agents that inhibit matrix metalloproteinases, and agents that modulate cyclin-dependent kinases. METHODS: The authors reviewed the available data for endostatin, COL-3, and flavopiridol, each of which is being developed ...
Growing evidence suggests that the proteasome may be dysfunctional in a number of neurodegenerative disorders, including Lewy body diseases. We have reported previously that application of pharmacological inhibitors of the proteasome to cultured cortical neurons leads to apoptotic death and formation of ubiquitinated cytoplasmic inclusions. A number of cell cycle regulatory proteins are known t...
Gd4O2S:Yb:Tm rare-earth upconversion phosphors have been utilised to monitor the redox behaviour of flavin mononucleotide and report on the turnover of a flavo-protein, (pentaerythritol tetranitrate reductase). The presence of two bands separated by over 300 nm in the UCP emission spectra allows ratiometric signalling of these processes with high sensitivity.
