Pemetrexed disodium shows the antiproliferative activity in CCRF-CEM leukemia, GC3/C1 colon carcinoma, and HCT-8 ileocecal carcinoma cells with IC50 of 25 nM, 34 nM and 220 nM, respectively. A recent study shows that cisplatin plus this compound combined with SOCS-1 gene delivery shows the antitumor effect by inhibition of cell proliferation, invasiveness, and induction of apoptosis in MPM cells infected with adenovirus-expressing SOCS-1 vector.
키나아제 분석
효소 분석 및 방법.
TS 활성은 생성물인 7,8-dihydrofolate의 형성에 따른 340 nm에서의 흡광도 증가를 모니터링하는 분광광도법을 사용하여 분석합니다. 분석 버퍼는 50 mM N-tris[hydroxymethyljmethyl-2-aminoethanesulfonic acid, 25 mM MgC12, 6.5 mM formaldehyde, 1 mM EDTA 및 75 mM 2-mercaptoethanol(pH 7.4)을 포함합니다. deoxyuridylate monophosphate, 6R-MTHF 및 hIS의 농도는 각각 100 μM, 30 μM 및 30 nM(1.7 milliunits/mL)입니다. 6R-MTHF 농도에서 저해되지 않은 반응과 6가지 농도의 억제제를 분석합니다. Ki app 값은 ENZFITTER 프로그램을 사용하여 비선형 회귀 분석으로 데이터를 Morrison 방정식에 피팅하여 결정합니다. Ki 값은 Ki app= Ki(1 + [S]/Km) 방정식을 사용하여 계산하며, 여기서 [S]는 30 μM이고 Km은 3 μM입니다. DHFR 활성은 340 nm에서 기질인 NADPH와 7,8-dihydrofolate가 소실되는 것을 모니터링하여 분광광도법으로 분석합니다. 반응은 25°C에서 150 mM KC1, 10 nM 2-mercaptoethanol(pH 7.5) 및 14 nM(0.34 milliunitlmL) DHFR을 포함하는 0.5 mL의 50 mM potassium phosphate 버퍼에서 수행됩니다. NADPH 농도는 10 μM이고 7,8-dihydrofolate 농도는 5, 10 또는 15 μM로 변화시킵니다. 각 7,8-dihydrofolate 농도에서 저해되지 않은 반응과 7가지 농도의 억제제를 분석합니다. ENZFITI'ER 마이크로컴퓨터 프로그램을 사용하여 비선형 회귀 분석으로 데이터를 Morrison 방정식에 피팅함으로써 Ki app 값을 얻습니다. Ki app= Ki(1 + [S]/Km) 식에서 [S]는 사용된 7,8-dihydrofolate의 농도와 같고 7,8-dihydrofolate의 Km은 0.15 μM입니다. GARFT 활성은 생성물인 5,8-dideazafolate 형성에 따른 295 nm에서의 흡광도 증가를 모니터링하여 분광광도법으로 분석합니다. 반응 용매는 25°C에서 75 mM HEPES, 20% glycerol 및 50 mM a-thioglygerol(pH 7.5)을 포함합니다. 사용된 기질 및 효소의 농도는 10 μM α,β-glycinamide ribonucleotide, 0-10 μM 10-formyl-5,8-dideazafolic acid 및 10 nM(1.9 milliunits/mL) GARFT입니다. Ki 값은 경쟁적 억제에 대한 Michaelis-Menten 방정식에 데이터를 피팅하기 위해 비선형 회귀 분석을 사용하는 Beckman DU640 분광광도계의 Enzyme Mechanism 프로그램을 사용하여 계산됩니다.
