The role of drug efflux and uptake transporters ABCB1 (P-gp), ABCG2 (BCRP) and OATP1A/1B and of CYP3A4 in the pharmacokinetics of the CDK inhibitor milciclib. (PubMed, Eur J Pharm Sci) - "Thus, ABCB1 and ABCG2 cooperatively limit milciclib brain penetration. The low impact of OATP1 and CYP3A could be clinically favorable for milciclib, reducing the risks of unintended drug-drug interactions or interindividual variation in CYP3A4 activity."

[VIRTUAL] Phospho-Proteomic Profiling of T-Cell Acute Lymphoblastic Leukemia Identifies Targetable Kinase Activities and Novel Treatment Combination Strategies (ASH 2020) - "The in vitro drug screening showed an effective response and G1-arrest following treatment with the CDK1/2 inhibitor milciclib in all the cell lines tested, with IC50 values between 10nM and 1uM...Interestingly, the concomitant inhibition of the SRC-family kinases by dasatinib and the INSR/IGF-1R axis by BMS-754807 led to a drastic reduction of cell viability at nanomolar concentrations even in cell lines that did not respond to dasatinib, identifying a novel possible effective combination strategy for T-ALL...Moreover, 70% of our PDXs efficiently responded to the broad spectrum kinase inhibitor midostaurin (IC50 < 1uM), highlighting the importance of targeting multiple signaling nodes simultaneously to tackle T-ALL vulnerabilities. Conclusions Ranking kinase activities and signaling networks from phospho-proteomic data can guide the use of PKIs as treatment option for T-ALL patients. Moreover, kinase activity profiling can provide insights for efficient treatment..."

An exon skipping screen identifies antitumor drugs that are potent modulators of pre-mRNA splicing, suggesting new therapeutic applications. (PubMed, PLoS One) - "Confirmatory assays showed that three clinical antitumor therapeutic candidates (milciclib, PF-3758309 and PF-562271) are potent splicing modulators and that these drugs are, in fact, nanomolar inhibitors of multiple kinases involved in the regulation the spliceosome. We also report the identification of new SF3B1 antagonists (sudemycinol C and E) and show that these antagonists can be used to develop a displacement assay for SF3B1 small molecule ligands. These results further support the broad potential for the development of agents that target the spliceosome for the treatment of cancer and other diseases, as well as new avenues for the discovery of new chemotherapeutic agents for a range of diseases."

Development and validation of an LC-MS/MS method for the quantitative analysis of milciclib in human and mouse plasma, mouse tissue homogenates and tissue culture medium. (PubMed, J Pharm Biomed Anal) - "Palbociclib, an analog compound, was used as internal standard. It is therefore recommended to keep these samples as briefly as possible at room temperature during the pre-treatment, and to store them at -70 °C to avoid analyte degradation. This method was successfully applied to support preclinical pharmacokinetic studies of milciclib."
