Flavopiridol (Alvocidib) vertoont minder activiteit tegen niet-gerelateerde kinasen zoals MAP, PAK, PKC en EGFR met IC50 >14 μM. Het remt significant de koloniegroei van HCT116, A2780, PC3 en Mia PaCa-2 cellen met IC50 van respectievelijk 13 nM, 15 nM, 10 nM en 36 nM. Deze verbinding remt ook krachtig de activiteit van Glycogeen synthase kinase-3 (GSK-3) met een IC50 van 280 nM. Vergeleken met andere CDK's remt het de activiteit van CDK7 minder krachtig met een IC50 van 875 nM. Bij 0,5 μM remt het zowel pSer807/811 Rb als pThr199 NPM, terwijl milde veranderingen worden waargenomen bij pThr821 Rb. Het verlaagt ook het totale RNA polymerase II-niveau, evenals de fosforylering van RNA polymerase II op de CTD-repeats bij Ser2 Ser5. Als een breed spectrum CDK-remmer kan het de Cell Cycle progressie in zowel G1 als G2 remmen. Bij 0,3 μM induceert het G1-arrest in zowel MCF-7 als MDA-MB-468 cellen door remming van de CDK4 of CDK2 kinase activiteit. Het vertoont krachtige cytotoxiciteit tegen een breed scala aan tumorcellijnen met IC50-waarden variërend van 16 nM voor LNCAP tot 130 nM voor K562.

CDK kinase-test

Voor de CDK1/cycline B1 kinase-test bestaan de kinase-reacties uit 100 ng van baculovirus-uitgedrukt GST-CDK1/cycline B1 (menselijk) complex, 1 μg histone HI, 0,2 μCi [γ-33P]ATP, 25 μM ATP in 50 μL kinasebuffer (50 mM Tris, pH 8,0, 10 mM MgCl2, 1 mM EGTA, 0,5 mM DTT). Voor de CDK2/cycline E kinase-test bestaan de kinase-reacties uit 5 ng van baculovirus-uitgedrukt GST-CDK2/cycline E (menselijk) complex, 0,5 μg GST-RB fusie-eiwit (aminozuren 776-928 van retinoblastoma-eiwit), 0,2 μCi [γ-33P]ATP, 25 μM ATP in 50 μL kinasebuffer (50 mM Hepes, pH 8,0, 10 mM MgCl2, 1 mM EGTA, 2 mM DTT). Voor de CDK4/cycline D1 kinase-test bestaan de kinase-reacties uit 150 ng van baculovirus-uitgedrukt GST-CDK4/cycline D1 (menselijk), 280 ng van Stag-cycline D1, 0,5 μg GST-RB fusie-eiwit (aminozuren 776-928 van retinoblastoma-eiwit), 0,2 μCi [γ-33P]ATP, 25 μM ATP in 50 μL kinasebuffer (50 mM Hepes, pH 8,0, 10 mM MgCl2, 1 mM EGTA, 2 mM DTT). Reacties worden gedurende 45 minuten voor CDK1 en CDK2, of 1 uur voor CDK4 bij 30 °C geïncubeerd en gestopt door de toevoeging van koud trichloorazijnzuur (TCA) tot een uiteindelijke concentratie van 15%. TCA-precipitaten worden verzameld op GF/C unifilterplaten met behulp van een Filtermate universele oogster en de filters worden gekwantificeerd met behulp van een TopCount 96-wells vloeistofscintillatieteller. Flavopiridol (Alvocidib) wordt opgelost in 10 mM dimethylformamide (DMF) en geëvalueerd bij zes concentraties, elk in drievoud. De uiteindelijke concentratie DMF in de test = 2%. IC50-waarden worden afgeleid door niet-lineaire regressieanalyse en hebben een variatiecoëfficiënt = 16%. Om de activiteit op CDK6 te testen, wordt een filterbindingsassay opgezet. Het volgende wordt gecombineerd in het reactiemengsel: 2 μL CDK6 (0,7 mg/μL), 5 μL histone H1 (6 mg/mL), 14 μL kinasebuffer (60 mM β-glycerofosfaat, 30 mM p-nitrofenylfosfaat, 25 mM MOPS (pH 7,0), 5 mM EGTA, 15 mM MgCl2, 1 mM DTT, 0,1 mM Na-vanadaat), 3 μL toenemende concentraties van deze verbinding verdund in 50% DMSO, en 6 μL 33P-ATP (1 mCi/mL) in niet-radioactief ATP bij 90 μM concentratie (uiteindelijke concentratie: 15 μM). De test wordt gestart door de toevoeging van 33P-ATP. De reactie wordt gedurende 20 minuten bij 30°C geïncubeerd. Een aliquot van 25 μL van het supernatant wordt vervolgens aangebracht op Whatman P81 fosfocellulosepapier. Filters worden 5 keer gewassen met 1% fosforzuuroplossing. Natte filters worden geteld in aanwezigheid van 1 mL scintillatievloeistof. CDK9-activiteit wordt gemeten met behulp van 50 nM recombinant CDK9/cycline T in 50 mM HEPES pH 7,5, 10 mM MgCl2, 1 mM DTT, 3 μM Na3VO4, 150 μM RNA polymerase CDT-peptide en 80 μM ATP. CDK7-test wordt uitgevoerd in dezelfde buffer met behulp van 37 nM gezuiverde kinase in aanwezigheid van 200 μM ATP en 10 μM myelinebindend eiwit als substraat. De potentie ervan ten opzichte van CDK9 en CDK7 wordt bepaald met behulp van ofwel een sterk anionenwisselaar (Dowex 1-X8 hars, formiaatvorm)-gebaseerde test of een scintillatie nabijheidsassay. IC50-waarden worden berekend uit de dosis-respons-curven.

Toediening van S1230 bij 7,5 mg/kg gedurende 7 dagen vertoont lichte antitumoractiviteit tegen P388 muizenleukemie, resulterend in een %T/C-waarde van 110, en is actief tegen het humane A2780 ovariumcarcinoom dat subcutaan is geïmplanteerd in naakte muizen, wat 1,5 log celvernietiging (LCK) produceert. S1230-behandeling bij 1-2,5 mg/kg gedurende 10 dagen onderdrukt significant collageen-geïnduceerde artritis bij muizen op een dosisafhankelijke manier, door synoviale hyperplasie en gewrichtsvernietiging te remmen, terwijl serumconcentraties van anti-collageen type II (CII) Abs en proliferatieve responsen op CII behouden blijven. In de p21-intacte Hct116-xenotransplantaten in naakte muizen, remt de toediening van CPT-11 (100 mg/kg), gevolgd door S1230 (3 mg/kg) 7 en 16 uur later, de tumorregressie significant met respectievelijk 86% en 82%, wat een >2-voudige remming vertoont in vergelijking met CPT-11 alleen met 40%. De combinatie produceert een volledig responspercentage (CR) van ~30% in tegenstelling tot CPT-11 alleen, waar geen CR wordt gevonden.
