β-2-Himachalen-6-ol inhibits 4T1 cells-induced metastatic triple negative breast carcinoma in murine model.

β-2-himachalen-6-ol (HC), a major sesquiterpene isolated from the Lebanese wild carrot umbels, was shown to possess remarkable in vitro and in vivo anticancer activities. The present study investigates the anti-metastatic activity of HC post 4T1 breast cancer cells inoculation in a murine model. The effect of HC on 4T1 cell viability was assessed using WST-1 kit, while cell cycle analysis was performed using flow cytometry.

Enhanced cellular uptake and photochemotherapeutic potential of a lipophilic strained Ru(ii) polypyridyl complex.

The use of ruthenium complexes as chemotherapeutic agents has been recently explored as one of the alternatives to conventional treatments. In the present study, two Ru(ii) polypyridyl complexes were synthesized and characterized: a strained [Ru(bipy)(BC)]Cl (complex 1) where [bipy = 2,2'-bipyridine and BC = bathocuproine] along with the unstrained control [Ru(bipy)(phen)]Cl (complex 2) where [phen = 1,10-phenanthroline]. The photophysical and photochemical analyses proved that unlike the photostable complex 2, complex 1 ejected both bipy and BC ligands at a ratio of 3 : 1 respectively.

The chemotherapeutic effect of β-2-himachalen-6-ol in chemically induced skin tumorigenesis.

β-2-himachalen-6-ol (HC), a novel sesquiterpene derived from Lebanese wild carrot, was shown to possess a remarkable anticancer activity. The present study investigates the in vitro anticancer activity of HC and its effect on papillomas induced using a DMBA/TPA skin carcinogenesis mouse model. HaCaT-ras II-4 epidermal squamous cell viability was assessed using WST-1 kit.

β-2-himachalen-6-ol protects against skin cancer development in vitro and in vivo.

Background: Previous studies in our laboratory showed that Daucus carota oil extract (DCOE) possesses remarkable in-vitro anticancer activity and antitumour promoting effect against DMBA/TPA skin carcinogenesis in mice. Chemical analysis of DCOE led to the isolation of the β-2-himachalen-6-ol (HC), major sesquiterpene with a potent anticancer activity against various colon, breast, brain and skin cancer cells. This study investigated the anticancer activity of HC against invasive epidermal squamous cell carcinoma cells and evaluated its effect in a DMBA/TPA skin carcinogenesis Balb/c murine model.

Antitumor activity of β-2-himachalen-6-ol in colon cancer is mediated through its inhibition of the PI3K and MAPK pathways.

Previous studies in our laboratory showed that Daucus carota oil extract (DCOE) possesses in vitro and in vivo anticancer activities. Chemical analysis of DCOE led to the isolation of β-2-himachalen-6-ol (HC) which exhibited potent anticancer activity against colon, breast, brain and skin cancer cells. The present study investigates the anticancer activity of HC against SW1116 colon cancer cell lines, and evaluates its effect in a 1,2-dimethylhydrazine (DMH) colon carcinogenesis black6 mice model.

Wild carrot pentane-based fractions suppress proliferation of human HaCaT keratinocytes and protect against chemically-induced skin cancer.

Background: Previous studies in our laboratory showed that the Lebanese Daucus carota ssp. carota (wild carrot) oil extract possesses in vitro and in vivo anticancer activities. The present study aims to examine the cytotoxic effect of Daucus carota oil fractions on human epidermal keratinocytes and evaluate the chemopreventive activity of the pentane diethyl ether fraction on DMBA/TPA induced skin carcinogenesis in mice.
