Biological Activity
| ln Vitro | After just 12 hours of treatment, 50% of the protein (DC50) of FKBP12 PROTAC RC32 (RC32; 0.1-1000 nM; 12 hours) is degraded [1]. |
| ln Vivo | In mouse organs treated for just one day, RC32 (RC32; i.p.; 30 mg/kg; twice daily; 1 day) suppresses the FKBP12 protein in all save the brain [1]. (Latoral: 60 mg/kg; twice daily; for a single day) lowers FKBP12 in mice by a considerable amount [1]. In the majority of the organs studied in 20 kg Bama pigs, RC32 (ip injection; 8 mg/kg; twice daily; for 2 days) efficiently breaks down the FKBP12 protein [1]. RC32 (ip injection; 8 mg/kg; twice daily; for 3 days) efficiently breaks down the heart, bone marrow, spleen, |
| Cell Assay |
Western Blot Analysis[1] Cell Types: Jurkat cells Tested Concentrations: 0.1, 1, 10, 100, 1000 nM Incubation Duration: 12 hrs (hours) Experimental Results: After only 12 hrs (hours) of treatment, protein degradation (DC50) was 50%, approximately 0.3 nM. |
| Animal Protocol |
Animal/Disease Models: Male and female mice [1] Doses: 30 mg/kg Route of Administration: IP; FKBP12 in lungs and stomach[1]. Twice a day; 1 day Experimental Results: FKBP12 protein was degraded in most organs of treated mice after only 1 day of treatment. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~10 mg/mL (~7.01 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: 1 mg/mL (0.70 mM) in 10% DMSO + 40% PEG300 +5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.0 mg/mL clear DMSO stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 + to the above solution and mix evenly; then add 450 μL of normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.  (Please use freshly prepared in vivo formulations for optimal results.) |
