The opium alkaloid noscapine is a commonly used antitussive agent available in Europe, Asia, and South America. Although the mechanism by which it suppresses coughing is currently unknown, it is presumed to involve the central nervous system. In addition to its antitussive action, noscapine also binds to tubulin and alters microtubule dynamics in vitro and in vivo. In this study, we show that n...

Paclitaxel is one of the most common chemotherapeutic drugs used for the treatment of prostate cancer. However, its current clinical utility has been limited due to numerous serious side effects and drug resistance. Noscapine is an antitussive opium alkaloid that showed antitumor activity against a variety of cancer while it has not exhibited severe side effects. This study investigates the ant...

Noscapine is an antitumor alkaloid from opium poppy that binds tubulin, arrests metaphase, and induces apoptosis in dividing human cells. Elucidation of the biosynthetic pathway will enable improvement in the commercial production of noscapine and related bioactive molecules. Transcriptomic analysis revealed the exclusive expression of 10 genes encoding five distinct enzyme classes in a high no...

OBJECTIVES Endometriosis is a complex gynecologic disease with unknown etiology. Noscapine has been introduced as a cancer cell suppressor. Endometriosis was considered as a cancer like disorder, The aim of present study was to investigate noscapine apoptotic effect on human endometriotic epithelial and stromal cells in vitro. MATERIALS AND METHODS In this in vitro study, endometrial biopsies...

Noscapine is a benzylisoquinoline alkaloid produced in opium poppy (Papaver somniferum) and other members of the Papaveraceae. It has been used as a cough suppressant and more recently was shown to possess anticancer activity. However, the biosynthesis of noscapine in opium poppy has not been established. A proposed pathway leading from (S)-reticuline to noscapine includes (S)-scoulerine, (S)-c...

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 crucial role in the control of tumor cell response to chemotherapeutic agents and DNA-damaging age...

Docetaxel (DOX) is one of the clinically used chemotherapeutic agents for treatment breast cancer, instead its severe side effects. Noscapine, an antitussive opium alkaloid, on other hand, has shown antitumor activity against a number cancers without any significant Since both compounds targeted tubulin, it interesting to see combined effect management cancer. The binding energy -3.49 and -4.18...

the present study aims to investigate the effect of noscapine (0.5-2.5 µm), an alkaloid from the opium poppy, on primary murine fetal cortical neurons exposed to oxygen–glucose deprivation (ogd), an in vitro model of ischemia. cells were transferred to glucose-free dmem (dulbecco's modified eagle medium) and were exposed to hypoxia in a small anaerobic chamber. cell viability and nitric ox...
