생물학적 활성

설명 Tipifarnib는 IC50 값이 0.6 nM인 강력하고 특이적인 farnesyltransferase (FTase) 억제제이며, H-ras 또는 N-ras 돌연변이 세포에서 항증식 효과가 가장 두드러집니다. 임상 3상.

시험관 내(In vitro)

Using Tipifarnib 5 μM for 72 hours, the percentage of apoptotic cells is significantly higher in drug-treated compared to DMSO-treated LGL T-cells. Using T-cells from healthy donors, this compound reduces the percentage of IFNγ-positive cells in a time-dependent manner. It reduces the amount of activated Ras in precipitates compared to DMSO. This chemical exerts selective in vitro toxicity against clonal MDS hematopoiesis at concentrations less than 10 nM the effect being more prominent in white cell progenitors. This action is not due to apoptosis induction as both normal and MDS progenitors displays equivalent DiOC3 and annexin V expression up to 72 hours after exposure to this compound. Combining it with 10 nM 4-OH-ICI 46474 in the presence of E2 reduces the IC50 8-fold from 400 to 50 nM. It induces apoptosis in U937 cells. In addition, this chemical inhibits isolated human farnesyltransferase for a lamin B peptide and for the K-RasB peptide with IC50 of 0.86 nM and 7.9 nM, respectively.

생체 내(In Vivo)

Ki-67 is lower in the tumors treated with E2 withdrawal plus this compound compared with E2 withdrawal alone. The combination of ICI 46474 and this chemical results in significantly lower Ki-67 compared with either ICI 46474 or this agent alone (mean of 5% versus 16.9% and 67.3%, respectively). In contrast, no significant difference in apoptotic scores is seen between the treatment groups. This compound alone also reduces the CTI compared with control. The combination of ICI 46474 and this agent or this chemical coupled with E2 withdrawal is most effective at lowering the CTI (0.8 and 0.7, respectively), which may account for the decrease in tumor volume.

Simvastatin/tipifarnib alters subcellular localization of RAS in human leukemia cells. Leukemia cells were treated with simvastatin (4 uM) and tipifarnib (1 uM), alone and in combination for 72hrs. Cytosolic and membrane fractions were prepared and western blot analysis was performed as described in the method section using the indicated antibodies. Calnexin was used as a membrane marker, whereas GAPDH is a marker of the cytosolic fraction. SIM, simvastatin. TIP, tipifarnib.

Effect of the inhibition of mutated RAS on thyroid cancer cell response to gefitinib . C-643 (RAS mutated thyroid cancer cells) and BC-PAP (wild type RAS thyroid cancer cells) were seeded in 96-well plates and incubated with increasing doses of gefitinib (Gef.; 0.5, 1.0 , and 5.0 uM), the RAS inhibitor tipifarnib (0.1, 1.0 and 10 uM) or both for 48 hours. Cell viability was then measured by the MTT assay.

The effects of SelleckChem inhibitors on sea urchin embryo development evaluated 24 h after fertilization. All compounds were added to embryos suspension 20 min after fertilization. The relative presence of late gastrula, swimming blastula, undeveloped embryos and dead embryos was compared next to untreated control embryos (A). Fertilized egg, swimming blastula and late gastrula are illustrated (B). The embryonic development was relatively synchronized in untreated control samples after 24 h (A, E). GSK690693 treatment sustained the development of embryos. Swimming blastulas kept normal motility regardless the deformities in their shape. Tipifarnib treatment induced significant toxicity due to occurrence of dead fragmented embryos. Some abnormal blastulas kept the motility. AZD2014 treatment sustained the development of embryos. Some developed gastrulas and blastulas were less motile in comparison with control (A, C). WZ811 was the least toxic compound. Significant number of gastrulas and blastulas was developed. However, their motility was considerably suppressed (A, D). In contrast to SelleckChem inhibitors, classic anticancer agent – cisplatin was extremely toxic to sea urchin embryos (A). Cisplatin killed many embryos, while a small amount of survived embryos was stopped at early phases of development: immediately after fertilization or after first and second division (A, F).
