chelerythrine/悪性腫瘍

A series of novel chelerythrine analogues was designed and synthesized. Antitumor activity was evaluated against A549, NCI-H1299, NCI-H292, and NCI-H460 non-small-cell lung cancer (NSCLC) cell lines in vitro. The selectivity of the most active analogues and chelerythrine was also evaluated, and we

OBJECTIVE A novel magnetic targeting anti-tumour drug delivery system (Fe3 O4 /KCTS-CHE) was designed using magnetic Fe3 O4 /chitosan alpha-ketoglutaric acid (Fe3 O4 /KCTS) as carrier and chelerythrine (CHE) as an anti-tumour drug model. Moreover, the anti-tumour activities and mechanisms of Fe3 O4

Previous studies have demonstrated that the benzo[c]phenanthridine alkaloid chelerythrine chloride (CC) has inhibitory effects on various tumors. However, the anticancer activity of CC and its underlying mechanisms have not been elucidated in renal cancer cells. The present study examined the

UNASSIGNED Prostate cancer is the most common noncutaneous cancer and the second leading cause of cancer-related mortality worldwide and the third in USA in 2017. Chelerythrine (CHE), a naturalbenzo[c]phenanthridine alkaloid, formerly identified as a protein kinase C inhibitor, has also shown

OBJECTIVE The aims of the present investigation were to evaluate the antitumor effect of chelerythrine (CHE) on in vivo growth and survival duration of BALB/c (H2d) mice bearing Dalton's lymphoma (DL) and enhanced function of tumor associated NK cells (TANK cells). METHODS BALB/c (H2d) mice at 8-10

Cervical cancer is the fourth most common female cancer worldwide, and drug targeted therapy plays a crucial role in delaying the progression of cervical carcinoma. Chelerythrine hydrochloride (CHE) is a natural alkaloid, which is a focal point in anti-tumor research. In this study, we investigated

Although clonogenic or divisional death is the main mechanism by which DNA-damaging agents demonstrate antitumor activity, recent data indicate that strategies specifically designed to trigger apoptosis may also prove to be useful antitumor agents. Protein kinase C (PKC) isoenzymes are involved in

Chelerythrine (CHE), a natural benzo[c]phenanthridine alkaloid, shows anti-cancer effect through a number of mechanisms. Herein, the effect and mechanism of the CHE-induced autophagy, a type II programmed cell death, in non-small cell lung cancer (NSCLC) cells were studied for the first time. CHE

Chelerythrine is a natural benzo[c]phenanthridine alkaloid found in many herbs and displays a wide range of antitumor activities. Here, the present study tested their effects on prostate cancer cells. The addition of chelerythrine can significantly inhibit the proliferation of androgen-independent

Quaternary benzo[c]phenanthridine alkaloids sanguinarine and chelerythrine have been used in folk medicine for their wide range of useful properties. One of their major effect is also anti-inflammatory activity, that is not clarified in detail. This study focused on the ability of these alkaloids to

Approximately 30% of cancer deaths result from the failure to control local and regional tumors. The goal of radiotherapy is to maximize local and regional tumor cell killing while minimizing normal tissue destruction. Attempts to enhance radiation-mediated tumor cell killing using halogenated

The efficacy of protein kinase inhibitors (PKIs) has been shown in clinical assays for cancer, but as isolated agents, they only have a modest effect. One of the most important characteristics of mitogen-activated PKIs is their ability to decrease the apoptotic threshold of cancer cells, sensitizing

Prostate cancer PC3 cells expressed constitutive protein kinase C (PKC) activity that under basal conditions suppressed neurotensin (NT) receptor function. The endogenous PKC activity, assessed using a cell-based PKC substrate phosphorylation assay, was diminished by PKC inhibitors and enhanced by

Cigarette smoke polyphenolic agents (catechol and hydroquinone) that generate oxidants have been shown to be tumor promoters. Furthermore, oxidants can influence protein kinase C (PKC)-mediated signal transduction. Since terpenoid tumor promoters, phorbol esters, increase invasion and metastasis by

A quaternary benzo [c] alkaloid chelerythrine (CHE), which is a traditional herbal prescription, has been used for the treatment of various inflammatory diseases. To gain insight into the anti-inflammatory effect and molecular mechanisms underlying the anti-inflammatory activity of CHE, we used
