  2. Ligands for Target Protein for PROTAC CDK
  3. TMX-3013

TMX-3013 is a CDK inhibitor capable of inhibiting the activity of CDK1, CDK2, CDK4, CDK5, and CDK6, with IC50 values of 0.9 nM, <0.5 nM, 24.5 nM, 0.5 nM, and 15.6 nM, respectively. TMX-3013 can be used as a target protein ligand, conjugated with the PROTAC linker and the CRBN ligand Thalidomide (HY-14658) for the synthesis of PROTAC TMX-2138 (HY-164906). TMX-3013 can also act as an effector ligand, binding to target proteins HaloTag or FKBP, and can be used in the synthesis of regulated induced proximity targeting chimeras (RIPTACs).

In Vitro

TMX-6PEG-CA, a TMX3013-based covalent RIPTAC, selectively inhibits the viability of HaloTag-FKBP-expressing 293_HFL cells with a GI50 of 0.050 μM[1].
TMX-6PEG-FKBP, a TMX3013-based non-covalent RIPTAC, selectively inhibits the viability of HaloTag-FKBP-expressing 293_HFL cells with a GI50 of 0.011 μM[1].
TMX-3013 is a non-covalent picomolar CDK2 inhibitor that functions as the CDK2 homing ligand for the generation of NASA-based acylation probes[2].
TMX-3013 potently inhibits CDK2/cyclin A (<0.5 nM IC50), CDK1/cyclin B (0.9 nM IC50), and CDK5/p25 (0.5 nM IC50), with reduced potency against CDK4/cyclin D1 (24.5 nM IC50) and CDK6/cyclin D1 (15.6 nM IC50) in biochemical assays[3].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 5 mg/mL (10.39 mM); Clear solution

    This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
