homoharringtonine/neoplasms

Homoharringtonine (HHT) is a cytotoxic alkaloid isolated from the evergreen tree cephalotaxus harringtonia native to the southern provinces of China. The principal mechanism of action of HHT is the inhibition of protein synthesis in a dose- and time-dependent manner by acting on the ribosomes of

Homoharringtonine (HHT) is an ester of cephalotaxine (CET), both of which derive from the Chinese coniferous tree Cephalotaxus hainanensis. HHT inhibited tumor cell growth at molar ranges comparable to established cytostatic drugs, whereas CET was 3-4 orders of magnitude less active. Inhibition

Overexpressed EphB4 conduce to tumor development and is regarded as a potential anticancer target. Homoharringtonine (HHT) has been approved for hematologic malignancies treatment, but its effect on hepatocellular carcinoma (HCC) has not been studied. This study elucidated HHT could restrain the

Harringtonine and its derivative homoharringtonine are ester-containing anti-leukemic alkaloids isolated from the tree Cephalotaxus harringtonia. In order to compare their antitumor activity against solid tumors, in vitro culture of fresh tumor cells from 23 patients was carried out with a soft agar

BACKGROUND One hallmark of cancer cells is their ability to evade physiologic signals causing regulated cell death (RCD). Correspondingly, TRAIL-based therapies to eliminate human cancer cells via enforced induction of apoptosis have been established and represent a promising approach in anti-cancer

Advanced subcutaneous Colon 38 tumours in mice were used for the assessment of activity of a number of anticancer drugs. Activity was measured by histological examination of tumours 24 h after a single dose of the drug and in some cases by tumour growth delay. Agents thought to exert their cytotoxic

Tyrosine kinase inhibitors (TKIs) are mostly used in non-small cell lung cancer (NSCLC) treatment. Unfortunately, treatment with Gefitinib for a period of time will result in drug resistance and cause treatment failure in clinic. Therefore, exploring novel compounds to overcome this resistance is

Triple negative breast cancers (TNBC) without BRCA1/2 gene mutation or BRCAness are nowadays the breast malignancies most difficult to treat. Improvement of their treatment, for all phases of the disease, is an important unmet medical need. We analyzed the effect of homoharringtonine (HHT), a

Homoharringtonine (HHT), an inhibitor of protein synthesis, has been used to treat leukemia. Its therapeutic effects on non-small cell lung adenocarcinoma carrying KRAS mutation and their immune system are less understood. The present study examined the therapeutic efficacy and the immune effects of

Twenty-four previously untreated, ambulatory patients with advanced colorectal carcinoma were treated with either caracemide (11 patients) or homoharringtonine (13 patients). No objective responses were observed in any of the treatment cohorts. Caracemide was well tolerated with the exception of one

Forty-eight previously untreated, ambulatory patients with advanced or unresectable renal carcinoma were treated with either amonafide (17 patients), caracemide (17 patients), or homoharringtonine (14 patients). No objective responses were observed in any of the treatment cohorts. Amonafide and

A phase II trial of Homoharringtonine (HHT) was performed in 15 patients with recurrent or progressive malignant glioma. The drug was administered at a initial dose of 4 mg/m2/day by continuous 5 day intravenous infusion (3 mg/m2/day x 5 days for heavily pretreated patients). Courses were repeated

Homoharringtonine, a plant alkaloid, has been reported to suppress protein synthesis and approved by U.S. Food and Drug Administration for chronic myeloid leukemia treatment. Here we show that homoharringtonine also potently inhibits cell growth/viability and induces cell cycle arrest and apoptosis

Renal cell carcinoma (RCC) accounts for 85% of primary renal neoplasms, and is rarely curable when metastatic. Approximately 70% of RCCs are clear-cell type (ccRCC), and in >80% the von Hippel-Lindau (VHL) gene is mutated or silenced. We developed a novel, high-content, screening strategy for the

The purpose of this study was to review the progress in clinical and translational research in chronic myelogenous leukemia (CML) over the past 20 years at M.D. Anderson Cancer Center. The CML database updating the clinical and basic research investigations was reviewed as the source of this report.
