Flavopiridol (Alvocidib) displays less activity against unrelated kinases such as MAP, PAK, PKC, and EGFR with IC50 of >14 μM. It significantly inhibits the colony growth of HCT116, A2780, PC3, and Mia PaCa-2 cells with IC50 of 13 nM, 15 nM, 10 nM and 36 nM, respecitively. This compound also potently inhibits the activity of Glycogen synthase kinase-3 (GSK-3) with an IC50 of 280 nm. Compared with other CDKs, it inhibits the activity of CDK7 less potently with IC50 of 875 nM. At 0.5 μM, it inhibits both pSer807/811 Rb and pThr199 NPM, whereas mild changes are observed at pThr821 Rb. It also decreases the overall RNA polymerase II level, as well as the phosphorylation of RNA polymerase II on the CTD repeats at Ser2 Ser5. As a broad spectrum CDK inhibitor, it can inhibit cell cycle progression in either G1 or G2. At 0.3 μM, it induces G1 arrest in either MCF-7 or MDA-MB-468 cells by inhibition of the CDK4 or CDK2 kinase activity. It exhibits potent cytotoxicity against a wide variety of tumor cell lines with IC50 values ranging form 16 nM for LNCAP to 130 nM for K562.

Für den CDK1/Cyclin B1-Kinase-Assay bestehen die Kinase-Reaktionen aus 100 ng des im Baculovirus exprimierten GST-CDK1/Cyclin B1 (human)-Komplexes, 1 μg Histon HI, 0,2 μCi [γ-33P]ATP, 25 μM ATP in 50 μL Kinase-Puffer (50 mM Tris, pH 8,0, 10 mM MgCl2, 1 mM EGTA, 0,5 mM DTT). Für den CDK2/Cyclin E-Kinase-Assay bestehen die Kinase-Reaktionen aus 5 ng des im Baculovirus exprimierten GST-CDK2/Cyclin E (human)-Komplexes, 0,5 μg GST-RB-Fusionsprotein (Aminosäuren 776-928 des Retinoblastom-Proteins), 0,2 μCi [γ-33P]ATP, 25 μM ATP in 50 μL Kinase-Puffer (50 mM Hepes, pH 8,0, 10 mM MgCl2, 1 mM EGTA, 2 mM DTT). Für den CDK4/Cyclin D1-Kinase-Assay bestehen die Kinase-Reaktionen aus 150 ng des im Baculovirus exprimierten GST-CDK4/Cyclin D1 (human), 280 ng Stag-Cyclin D1, 0,5 μg GST-RB-Fusionsprotein (Aminosäuren 776-928 des Retinoblastom-Proteins), 0,2 μCi [γ-33P]ATP, 25 μM ATP in 50 μL Kinase-Puffer (50 mM Hepes, pH 8,0, 10 mM MgCl2, 1 mM EGTA, 2 mM DTT). Die Reaktionen werden 45 Minuten für CDK1 und CDK2 oder 1 Stunde für CDK4 bei 30 °C inkubiert und durch Zugabe von kalter Trichloressigsäure (TCA) bis zu einer Endkonzentration von 15 % gestoppt. TCA-Präzipitate werden auf GF/C-Unifilterplatten mit einem Filtermate Universal Harvester gesammelt und die Filter mit einem TopCount 96-Well Flüssigkeitsszintillationszähler quantifiziert. Flavopiridol (Alvocidib) wird in 10 mM in Dimethylformamid (DMF) gelöst und in sechs Konzentrationen, jeweils dreifach, evaluiert. Die Endkonzentration von DMF im Assay beträgt 2 %. Die IC50-Werte werden durch nichtlineare Regressionsanalyse abgeleitet und haben einen Variabilitätskoeffizienten von 16 %. Zur Bestimmung seiner Aktivität auf CDK6 wird ein Filterbindungsassay etabliert. Die folgenden Komponenten werden in der Reaktionsmischung kombiniert: 2 μL CDK6 (0,7 mg/μL), 5 μL Histon H1 (6 mg/mL), 14 μL Kinase-Puffer (60 mM β-Glycerophosphat, 30 mM p-Nitrophenylphosphat, 25 mM MOPS (pH 7,0), 5 mM EGTA, 15 mM MgCl2, 1 mM DTT, 0,1 mM Na-Vanadat), 3 μL zunehmender Konzentrationen dieser in 50 % DMSO verdünnten Verbindung und 6 μL 33P-ATP (1 mCi/mL) in nichtradioaktivem ATP bei 90 μM Konzentration (Endkonzentration: 15 μM). Der Assay wird durch Zugabe von 33P-ATP initiiert. Die Reaktion wird 20 Minuten bei 30 °C inkubiert. Ein 25 μL Aliquot des Überstands wird dann auf Whatman P81 Phosphocellulose-Papier aufgetragen. Die Filter werden 5 Mal mit 1 %iger Phosphorsäurelösung gewaschen. Feuchte Filter werden in Gegenwart von 1 mL Szintillationsflüssigkeit gezählt. Die Cdk9-Aktivität wird unter Verwendung von 50 nM rekombinantem Cdk9/Cyclin T in 50 mM HEPES pH 7,5, 10 mM MgCl2, 1 mM DTT, 3 μM Na3VO4, 150 μM RNA-Polymerase CDT-Peptid und 80 μM ATP gemessen. Der Cdk7-Assay wird im selben Puffer unter Verwendung von 37 nM gereinigter Kinase in Gegenwart von 200 μM ATP und 10 μM Myelin-Bindungsprotein als Substrat durchgeführt. Die Wirksamkeit gegenüber CDK9 und CDK7 wird entweder mittels eines starken Anionenaustauscher-(Dowex 1-X8 Harz, Formiat-Form)-basierten Assays oder eines Szintillationsproximity-Assays bestimmt. Die IC50-Werte werden aus den Dosis-Wirkungs-Kurven berechnet.

| In vivo |
Administration of S1230 at 7.5 mg/kg for 7 days displays slight antitumor activity against P388 murine leukemia, resulting in %T/C value of 110, and active against the human A2780 ovarian carcinoma implanted sc in nude mice, producing 1.5 log cell kill (LCK). S1230 treatment at 1-2.5 mg/kg for 10 days significantly suppresses collagen-induced arthritis in mice in a dose-dependent manner, by inhibiting synovial hyperplasia and joint destruction, whereas serum concentrations of anti-collagen type II (CII) Abs and proliferative responses to CII are maintained. In the p21-intact Hct116 xenografts in nude mice, administration of CPT-11 (100 mg/kg) followed by S1230 (3 mg/kg) 7 and 16 hours later significantly inhibits tumor regression by 86% and 82%, respectively, displaying >2 fold inhibition compared with CPT-11 alone by 40 %. The combination produces ~30% complete response rate (CR) in contrast to CPT-11 alone where no CR is found.
