Insights

New halogenated Coelenterazine derivatives show potent anticancer activity against gastric and lung cancer. Brominated Coelenteramine (Br-Clm) demonstrated efficacy with a favorable safety profile, inducing apoptosis in cancer cells.

Area of Science:

  • Marine natural products chemistry
  • Medicinal chemistry
  • Cancer biology

Background:

  • Cancer treatment faces challenges due to side effects and limited therapeutic efficiency.
  • The bioluminescent system of Coelenterazine offers a source for novel therapeutic molecules.
  • Investigating halogenated derivatives of Coelenterazine components is a promising avenue for drug discovery.

Purpose of the Study:

  • To explore the anticancer activity of halogenated derivatives of Coelenterazine (Clz), Coelenteramide (Clmd), and Coelenteramine (Clm).
  • To identify potent anticancer compounds with potential therapeutic applications against specific cancer types.
  • To characterize the mechanism of action and structure-activity relationships of promising candidates.

Main Methods:

  • Synthesis and characterization of halogenated Coelenterazine derivatives.
  • In vitro screening of compounds against gastric and lung cancer cell lines.
  • Evaluation of cytotoxicity against non-cancer cells.
  • Apoptosis induction assays and pathway analysis.
  • Structure-activity relationship (SAR) studies.

Main Results:

  • Coelenterazine derivatives exhibited variable anticancer activity against gastric and lung cancer cells.
  • Brominated Coelenteramide (Br-Clmd) and brominated Coelenteramine (Br-Clm) showed the highest potency.
  • Br-Clm demonstrated a favorable safety profile towards non-cancer cells.
  • Br-Clm induced cancer cell death via apoptosis, involving both intrinsic and extrinsic pathways.
  • Key structural features contributing to Br-Clm's anticancer activity were identified.

Conclusions:

  • Halogenated Coelenterazine derivatives represent a novel class of anticancer agents.
  • Br-Clm is a promising lead compound for the development of new chemotherapeutic agents against gastric and lung cancer.
  • Further optimization of Br-Clm and related structures could lead to improved therapeutic efficacy and safety profiles.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...
