From Celebrex to a Novel Class of Phosphoinositide-Dependent Kinase 1 (Pdk-1) Inhibitors for Androgen-Independent Prostate Caner
FROM CELEBREX TO A NOVEL CLASS OF PHOSPHOINOSITIDE-DEPENDENT KINASE 1 (PDK-1) INHIBITORS FOR ANDROGEN-INDEPENDENT PROSTATE CANER DISSERTATION Presented in Partial Fulfillment of the requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Jiuxiang Zhu, M.S. * * * * * The Ohio State University 2005 Dissertation Committee: Approved by Professor Ching-Shih Chen, Advisor Professor Robert Brueggemeier Advisor Professor Pui-Kai (Tom) Li Graduate Program in Pharmacy Professor Matthew D. Ringel ABSTRACT Celebrex, a nonsteroidal anti-inflammatory drug (NSAID, cyclooxygenase-2 inhibitor), was reported to induce apoptosis in the prostate cancer cell line PC-3 at 50µM. Early research from our laboratory demonstrated that this apoptotic inducing effect was independent of its COX-2 inhibitory activity. Further investigation showed that PDK-1 was a major protein targeted by celebrex in PC-3 cells to induce apoptosis. However, celebrex was very weak in inhibiting PDK-1 with IC50 of 48µM. To improve its potency, two series of analogs were designed and synthesized. In the first series of 24 compounds, the 5-position methylphenyl moiety of celebrex was replaced by various aromatic ring systems to explore the optimal hydrophobic group. OSU02067 (IC50=9µM) with phenanthrene at the 5-position was the best inhibitor among this series and was selected as the lead compound for further modification. Enzyme kinetics study of PDK-1 inhibition by celebrex indicated that it competed with ATP for binding. Docking of OSU02067 into the ATP binding domain of PDK-1 showed that the sulfonamide moiety hydrogen bonded to hinge region residue Ala162. -
Chemotherapy Protocol
Chemotherapy Protocol BREAST CANCER CYCLOPHOSPHAMIDE-EPIRUBICIN-PACLITAXEL (7 day) Regimen • Breast Cancer – Cyclophosphamide-Epirubicin-Paclitaxel (7 day) Indication • Neoadjuvant / adjuvant therapy of early breast cancer • WHO Performance status 0, 1 Toxicity Drug Adverse Effect Cyclophosphamide Dysuria, haemorrhagic cystitis, taste disturbances Epirubicin Cardio-toxicity, urinary discolouration (red) Hypersensitivity, hypotension, bradycardia, peripheral Paclitaxel neuropathy, myalgia and back pain on administration The adverse effects listed are not exhaustive. Please refer to the relevant Summary of Product Characteristics for full details. Monitoring Regimen • FBC, U&Es and LFTs prior to each cycle. • Ensure adequate cardiac function before starting treatment with epirubicin. Baseline LVEF should be measured, particularly in patients with a history of cardiac problems or in the elderly. Dose Modifications The dose modifications listed are for haematological, liver and renal function only. Dose adjustments may be necessary for other toxicities as well. In principle all dose reductions due to adverse drug reactions should not be re- escalated in subsequent cycles without consultant approval. It is also a general rule for chemotherapy that if a third dose reduction is necessary treatment should be stopped. Please discuss all dose reductions / delays with the relevant consultant before prescribing if appropriate. The approach may be different depending on the clinical circumstances. The following is a general guide only. Version 1.2 (November 2020) Page 1 of 7 Breast – Cyclophosphamide-Epirubicin-Paclitaxel (7 day) Haematological Prior to prescribing the following treatment criteria must be met on day one of treatment. Criteria Eligible Level Neutrophils equal to or more than 1x10 9/L Platelets equal to or more than 100x10 9/L Consider blood transfusion if patient symptomatic of anaemia or has a haemoglobin of less than 8g/dL If counts on day one are below these criteria for neutrophils and platelets then delay treatment for seven days. -

ISM is based on (i) molecular profi ling and ex vivo drug sensitivity and resistance testing (DSRT) of patients’ cancer cells to 187 oncology drugs, (ii) clinical implementation of therapies predicted to be effective, and (iii) studying consecutive samples from the treated patients to understand the basis of resistance. Here, application of ISM to 28 samples from patients with acute myeloid leukemia (AML) uncovered fi ve major taxonomic drug-response sub- types based on DSRT profi les, some with distinct genomic features (e.g., MLL gene fusions in subgroup IV and FLT3 -ITD mutations in subgroup V). Therapy based on DSRT resulted in several clinical responses. -
