BACKGROUND
Noscapine, a non-toxic alkaloid and common constituent of cough medicine, stabilises tubulin. It inhibits the growth of several human and murine neoplasms, with no significant toxicity. Its effect on prostate cancer has not been evaluated.
METHODS
Noscapine was administered orally (300
Noscapine (Nos), an orally available plant-derived antitussive alkaloid, is in phase II clinical trials for cancer chemotherapy. It has extensively been shown to inhibit tumor growth in nude mice bearing human xenografts of hematopoietic, breast, lung, ovarian, brain, and prostate origin. However,
Noscapine, a naturally occurring alkaloid obtained from opium poppy, is a microtubule-targeting agent. This study is aimed to investigate the effects of noscapine on human breast cancer cell lines by comparing them with those of tamoxifen and Previous report of the vast effectiveness of opium derivatives in cancer therapy is leading us to see possible effects of these derivatives on cancer stem cells in order to find new agent for cancer therapy. In this study, cells were stained for CSC markers and sorted by magnetic beads. CSCs exhibit
OBJECTIVE
An antitussive plant alkaloid, Noscapine HCl (Nos) displays anticancer activity and has a safe pharmacological profile in humans. The current study was aimed to investigate the in vitro and in vivo anti tumor activity of Nos to determine possible mechanisms of anti tumor activity for
We have previously identified the naturally occurring non-toxic antitussive phthalideisoquinoline alkaloid, noscapine as a tubulin-binding agent that arrests mitosis and induces apoptosis. Here we present high-yield efficient synthetic methods and an evaluation of anticancer activity of halogenated
Noscapine, a tubulin binding anticancer agent undergoing Phase I/II clinical trials, inhibits tumor growth in nude mice bearing human xenografts of breast, lung, ovarian, brain, and prostrate origin. The analogues of noscapine like 9-bromonoscapine (EM011) are 5 to 10-fold more active than parent
We have previously discovered the naturally occurring antitussive alkaloid noscapine as a tubulin-binding agent that attenuates microtubule dynamics and arrests mammalian cells at mitosis via activation of the c-Jun NH(2)-terminal kinase pathway. It is well established that the p53 protein plays a
BACKGROUND
The aim of this investigation was to evaluate the anticancer activity of Noscapine (Nos) and Gemcitabine (Gem) combination (NGC) against non-small cell lung cancer (NSCLC) and to elucidate the underlying mechanism of action.
METHODS
Isobolographic method was used to calculate combination
The purpose of this study was to examine the efficacy of Noscapine (Nos) and Cisplatin (Cis) combination treatment in vitro in A549 and H460 lung cancer cells, in vivo in murine xenograft model and to investigate the underlying mechanism. The combination index values (< 0.6) suggested synergistic
We have shown previously that an antitussive plant alkaloid, noscapine, binds tubulin, displays anticancer activity, and has a safe pharmacological profile in humans. Structure-function analyses pointed to a proton at position-9 of the isoquinoline ring that can be modified without compromising
Systematic screening based on structural similarity of drugs such as colchicine and podophyllotoxin led to identification of noscapine, a microtubule-targeted agent that attenuates the dynamic instability of microtubules without affecting the total polymer mass of microtubules. We report a new
Our screen for tubulin-binding small molecules that do not depolymerize bulk cellular microtubules, but based upon structural features of well known microtubule-depolymerizing colchicine and podophyllotoxin, revealed tubulin binding anti-cancer property of noscapine (Ye et al. in Proc Natl Acad Sci
Noscapine is an isoqiunoline alkaloid found in opium latex. Unlike most other alkaloids obtained from opium latex, noscapine is not sedative and has been used as antitussive drug in various countries. Recently, it has been introduced as an anti-mitotic agent. This drug can be used orally. When the
Noscapine, a common oral antitussive agent, has been shown to have potent antitumor activity in a variety of cancers. Treatment of glioblastoma multiforme (GBM) with temozolomide (TMZ), its current standard of care, is problematic because the tumor generally recurs and is then resistant to this
