Summary
New diterpenoid alkaloids from Delphinium trichophorum Franch. were isolated and tested for cytotoxic activity. Some compounds showed moderate cytotoxicity against A549 cancer cells.
Area of Science:
- Natural Product Chemistry
- Pharmacology
Background:
- Delphinium species are a rich source of bioactive alkaloids.
- Diterpenoid alkaloids, including hetisane and delnudine types, are known for diverse biological activities.
Purpose of the Study:
- To isolate and characterize novel diterpenoid alkaloids from Delphinium trichophorum Franch.
- To evaluate the cytotoxic potential of isolated compounds against cancer cell lines.
Main Methods:
- Isolation of compounds using chromatographic techniques.
- Structure elucidation via extensive spectroscopic analysis (HSQC, HMBC, COSY, NOESY) and X-ray crystallography.
- Cytotoxicity assessment using the MTT assay against A549 cancer cells.
Main Results:
- Five new hetisane-type (trichodelphinines A-E) and one new delnudine-type (trichodelphinine F) diterpenoid alkaloids were identified.
- Three known flavonoids were also isolated.
- The isolated diterpenoid alkaloids exhibited cytotoxic activities with IC50 values ranging from 12.03 to 52.79 μM against A549 cancer cells.
Conclusions:
- Delphinium trichophorum Franch. is a valuable source of structurally diverse diterpenoid alkaloids.
- The novel alkaloids possess moderate cytotoxic properties, warranting further investigation for anticancer drug development.

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...

2.2K
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...

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
