Biological Activity

Description LDC4297 is a novel CDK7 inhibitor (IC50=0.13±0.06 nM for CDK7 versus IC50s between 10 nM and 10,000 nM for all other analyzed CDKs).
Targets
CDK7 [1]
(Cell-free assay)
0.13 nM
In vitro
In vitro LDC4297 inhibits CDK7 in vitro in the nano-picomolar range. The affinity of LDC4297 for CDK7 proves to be extremely high. The replication of HCMV in cultured primary human fibroblasts (HFFs) is inhibited by LDC4297 in a concentration-dependent manner with a 50% effective concentration (EC50) value of 24.5 ± 1.3 nM. Notably, CDK7 inhibition by LDC4297 is not associated with general cytotoxicity at submicromolar concentrations. In contrast, LDC4297 induces cytotoxicity in a set of tumor cell lines, i.e., already at extremely low, nanomolar concentrations in specific cases. Anti-HCMV activity of LDC4297 is exerted through a multifaceted mode of action that involves an interference with virus-induced Rb phosphorylation[1].
Cell Research Cell lines human fibroblasts
Concentrations 0.1 to 50 μM
Incubation Time 3 days
Method A trypan blue exclusion assay is performed with cultured cells seeded in 24-well plates and incubated with increasing concentrations of antiviral compounds (range, 0.1 to 50 μM) for the durations indicated. Cell staining is achieved with 0.1% trypan blue for 10 min at room temperature before the percentage of viable cells is determined by microscopic counting.
In Vivo
In vivo The PK analyses of LDC4297 performed thus far have also been highly promising. An analysis of the PK parameters in CD1 mice reveals positive characteristics after oral administration, as demonstrated for a single-dose treatment (100 mg/kg of LDC4297. The half-life (t1/2z) is determined to be 1.6 h, and a time (Tmax) to a mean peak plasma concentration of 1,297.6 ng/ml is reached 0.5 h after administration, with a continued presence of LDC4297 plasma levels for at least 8 h and a bioavailability of 97.7%[1].

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
