Summary
Crinum zeylanicum alkaloids show significant anticancer potential. Crinine demonstrated potent antiproliferative and apoptosis-inducing effects against human tumor cells, highlighting its therapeutic promise.
Area of Science:
- Phytochemistry
- Pharmacology
- Medicinal Chemistry
Background:
- Crinum zeylanicum holds traditional medicinal uses.
- Its complex alkaloid composition is recognized.
- Alkaloids are known for diverse biological activities.
Purpose of the Study:
- To isolate and identify bioactive alkaloids from Crinum zeylanicum.
- To evaluate the antiproliferative and cytotoxic effects of these alkaloids on human tumor cell lines.
- To explore structure-activity relationships of the isolated compounds.
Main Methods:
- Gas Chromatography-Mass Spectrometry (GC-MS) for alkaloid profiling.
- Isolation and purification of specific alkaloid compounds.
- In vitro assays to determine antiproliferative activity (IC50) and apoptosis induction.
Main Results:
- Several alkaloids including crinine, lycorine, and 6-hydroxybuphanidrine were isolated.
- Crinine, 6-hydroxybuphanidrine, and 6-ethoxybuphanidrine exhibited antiproliferative effects.
- Crinine showed the highest activity (IC50 14.04 μM against HL-60/Dox) and induced apoptosis in cancer cell lines.
- Structure-activity relationship analysis revealed key modifications impacting cytotoxicity.
Conclusions:
- Crinum zeylanicum alkaloids, particularly crinine, possess significant anticancer properties.
- Crinine's ability to induce apoptosis warrants further investigation for cancer therapy.
- Understanding structure-activity relationships can guide the development of novel anticancer agents.

01:10Drugs that Destabilize Microtubules
Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...
01:15Anthelminthic Agents
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
01:15Drugs that Stabilize Microtubules
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...
02:34Inhibition of Cdk Activity
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
