OBJECTIVE
QC4 is the derivative of rosin's main components dehydroabietic acid (DHA). We investigated the cytotoxic effect of QC4 on gastric cancer cells and revealed the mechanisms beneath the induction of cell death.
METHODS
The cytotoxic effect of QC4 on gastric cancer cells was evaluated by
Liver cancer has become the third type of cancer that causes death; this is why the design of new chemotherapeutic drugs against this disease is a major need. With this idea, a series of Dehydroabietic Acid-Based Acylhydrazones have been used to generate a CoMFA model to design new anticancer
Pinecones from Pinus koraiensisSiebold & Zucc. (Pinaceae), which have historically been treated as an undesired waste by-product in the processing of seeds, have recently been shown to contain ingredients with potent biological activities, such as polyphenols exhibiting antitumor activity. With this
Terpenoids, which are contained in a large number of dietary and herbal plants, have many biological effects. In this study, the effects of dehydroabietic acid (DAA), a diterpene, on glucose and lipid metabolism were examined using obese diabetic KK-Ay mice. We showed here that DAA treatment
Wound healing impairment is a well-documented phenomenon in clinical and experimental diabetes, and in diabetic wound healing impaired fibroblast has been linked to increased levels of tumor necrosis factor-α (TNF-α). A number of signaling pathways including TNF-α/forkhead box O1 (FOXO1) and
Novel representatives of the important group of biologically-active, dehydroabietic acid-bearing oxazolidinone moiety were synthesized to explore more efficacious and less toxic antitumor agents. Structures of all the newly target molecules were confirmed by IR, ¹H-NMR, 13C-NMR, and HR-MS. The
In an attempt to search for new natural product-based antitumor agents, a series of novel (aryl)methyl-amine derivatives of dehydroabietic acid-based B ring-fused-thiazole were designed and synthesized. The primary bioassay showed that compounds 5r and 5s presented certain inhibitory activity
Natural resin acids present in rosin of Pinus spez., including isopimaric acid (1), mercusic acid (2), neoabietic acid (3), dehydroabietic acid (4), and podocarpic acid (8), as well as resin acid derivatives 8β,9α,13α-H-tetrahydroabietic acid (5), 8α,9α,13α-H-tetrahydroabietic acid (6),
In order to develop novel chemotherapeutic agents with potent anticancer activities, a series of dehydroabietic acid (DHA) derivatives bearing an acylhydrazone moiety were designed and synthesized by the condensation between dehydroabietic acylhydrazide (3) and a variety of substituted
Three biflavonoids [cupressuflavone (1), amentoflavone (2), and sumaflavone (3)], four diterpenoids [13-epi-cupressic acid (4), imbricatholic acid (5), 3-hydroxy-sandaracopimaric acid (6), and dehydroabietic acid (7)], and one lignan [β-peltatin methyl ether (8)] were isolated from the cytotoxic
A series of novel dehydroabietic acid (DHA) chiral dipeptide derivatives were designed and synthesized as potent antitumor agents. The inhibitory activities of these compounds against NCI-H460 (lung), HeLa (epithelial cervical) and MGC-803 (gastric) human cancer cell lines were estimated by MTT
A concise and efficient synthetic approach has been established to readily access a series of novel C-14 1,2,3-triazole-tethered dehydroabietic acid derivatives in moderate to high yields. In vitro antiproliferative activity evaluation indicated that most of the hybrids exhibited potent inhibitory
A series of new quinoxaline derivatives of dehydroabietic acid (DAA) were designed and synthesized as potential antitumor agents. Their structures were characterized by IR, ¹H-NMR, 13C-NMR, and MS spectra and elemental analyses. All the new compounds were screened for their in vitro
The structures of two novel 3,4-seco-lanostane-type triterpenes isolated from the sclerotium of Poria cocos were established to be 16alpha-hydroxy-3,4-seco-lanosta-4(28),8,24-triene-3,21-dioic acid (1; poricoic acid G) and 16alpha-hydroxy-3,4-seco-24-methyllanosta-4(28),8,24(24(1))-triene-3,21-dioic
Phosphatidylinositol 3-kinase (PI3K) is one of the most attractive therapeutic targets for cancer treatment. In this study, a series of new 2-arylthio- and 2-arylamino-1H-benzo[d]imidazole derivatives of dehydroabietic acid were designed, synthesized and characterized by 1H NMR,
