lantadene a/neoplasms

Gold nanoparticles (AuNPs) have been widely used in many applications. Their usage as drug delivery vehicles has also gained considerable attention due to their chemical and optical properties as well as their good biocompatibility. The present study was conducted to evaluate the efficiency of AuNPs

Pentacyclic triterpenoid lantadene A congener with hydroxyl functionality in ring A was designed and synthesised on the basis of enhancement of polarity and bioactivity. The new synthesised compound 22β-angeloyloxy-methyl-2-hydroxy-3-oxoolean-1,12-dien-28-oate (6) was screened for cytotoxicity

Five new derivatives of the pentacyclic triterpenoid lantadene A (= 22beta-angeloyloxy-3-oxoolean-12-en-28-oic acid; 1) from the leaves of Lantana camara L. were synthesized, characterized, and screened for their cytotoxicities against four human cancer cell lines. The three most-potent compounds,

The ring A and D substituted analogs of pentacyclic triterpenoid Lantadene A (1) and B (2) were synthesized and evaluated for in vitro anticancer activity against four human cancer cell lines (HL-60, MCF-7, A549 and HCT-116). Analogs 3, 4, 7 and 8 showed enhanced inhibitory activity as compared with

Lantana camara is an important medicinal plant that contains many active compounds, including pentacyclic triterpenoids, with numerous biological activities. The present study was conducted to evaluate the anti-oxidant, anti-tumour, and cell cycle arrest properties of chemical compounds extracted

The antitumor pentacyclic triterpenoids, Lantadene A (1) and B (2) were isolated from the leaves of weed Lantana camara L. (Verbenaceae) and were structurally transformed to bioactive intermediates 3-6. The Claisen-Schmidt reaction of 22β-hydroxy-3-oxoolean-12-en-28-oic acid (5) with requisite

Lantadenes are pentacyclic triterpenoids isolated from leaves of Lantana camara L. and have antitumor activity. Lantadene A (LA) and methyl ester of LA (LAM) were earlier studied in the author's lab for their chemopreventive effect on 7,12-dimethylbenz(a)anthracene (DMBA) followed by

The activation of transcription factors nuclear factor-kappa B (NF-κ B) and cyclooxygenase-2 (COX-2) is critical in cancer; they act synergistically in promoting tumor growth, survival, and resistance to chemotherapy. Thus, combined targeting of NF-κ B and COX-2 present an opportunity for
