AI Article Synopsis

  • - Ten new flavonoids, called denticulains A-J, were discovered in the plant Macaranga denticulata, along with seven previously known flavonoids.
  • - The structures of these compounds were determined using advanced techniques and by comparing them with existing data.
  • - Two specific compounds (denticulain A and another known flavonoid) showed the ability to inhibit cancer cell growth in lab tests, with respective IC values of 46.08 μM and 56.83 μM.

Article Abstract

Ten new prenylated flavonoids, named denticulains A-J (1-10), together with seven known prenylated flavonoids (11-17) were isolated from Macaranga denticulata. Their structures were elucidated on the basis of detailed spectroscopic analysis and by comparison with literature data. In addition, compounds 1 and 14 inhibited the proliferation of SW620 and HCT-116 cell lines with an IC value of 46.08 μM and 56.83 μM, respectively.

Prostate cancer remains a significant global health concern, prompting ongoing exploration of novel therapeutic agents. Licochalcone A, a natural product in the chalcone family isolated from licorice root, is characterized by its enone structure and demonstrates antiproliferative activity in the micromolar range across various cell lines, including prostate cancer. Building on our prior success in enhancing curcumin's antiproliferative potency by replacing the substituted phenol with a 1-alkyl-1H-imizadol-2-yl moiety, we applied a similar approach to design a new class of licochalcone A-inspired chalcones.

Much attention has been paid to the potential biological activities of prenylated flavonoids (PFs) in various plant families over the last decade. They have enormous potential for biological activities, such as anti-cancer, anti-diabetic, antimicrobial, anti-inflammatory, anti-Alzheimer's, and neuroprotective activities. Medicinal chemists have recently shown a strong interest in PFs, as they are critical to the development of new medicines.

Prenylation, which involves the addition of hydrophobic molecules, is considered to enhance the bioavailability and biological activity of flavonoids. However, the effect of prenylation on the estrogenic activity of flavonoids with different structures remains unclear. This study evaluated the estrogen receptor-α (ER-α) agonistic and antagonistic activities of estrogenic flavonoids in both unprenylated and prenylated forms using OECD standardized in vitro ER-α transactivation assay and in vivo uterine hypertrophy assay.

Background: A prenylated flavonoid, broussoflavonol F (BFF), was isolated from Macaranga genus with cytotoxicities against various cancer cells, though its underlying mechanisms have not been fully elucidated.

Hypothesis: This study aimed to investigate the anti-tumor and anti-angiogenesis activities of BFF and its underlying mechanisms in colon cancer.

Method: In the in vitro study, the cytotoxic effects of BFF in human colon cancer HCT-116 and LoVo cells were examined using MTT assay, BrdU assay and colony formation assay.
