Biological Activity
| ln Vitro | PHGDH-IN-3 (compound D8) exhibits strong enzymatic inhibitory action, as evidenced by its IC50 value of 2.8 μM[1]. PHGDH-IN-3 exhibits a strong affinity for PHGDH protein, as evidenced by its Kd value of 2.33 μM [1]. Antibiotic-induced de novo serine synthesis in MDA-MB-468 cells can be inhibited by PHGDH-IN-3 [1]. |
| ln Vivo | PHGDH-IN-3 (compound D8) (po, iv; 1, 3 mg/kg) exhibits excellent domestic pharmacokinetic properties [1]. PHGDH-IN-3 (ip; 12.5, 25, 50 mg/) kg; once a day for 31 consecutive days) exerts a significant anti-tumor effect in the PC9 xenograft mouse model [1]. |
| Animal Protocol |
Animal/Disease Models: ICR mouse[1] Doses: 1, 3 mg/kg Route of Administration: Oral (po) and intravenous (iv) (iv)(iv) Administration Experimental Results: PK parameters iv (1 mg/kg) po (3 mg/kg ) AUC (h·ng/mL) 38,358 ± 14,768 94,386 ± 23,416 T1/2(h) 4.94 ± 0.38 4.74 ± 0.30 Tmax (h) 3.33 ± 1.15 CL_obs(mL/min/kg) 0.48 ± 0.23 Cmax(ng/mL ) 8842 ± 1755 F (%) 82.0 Animal/Disease Models: Balb/c nude mice [1] Doses: 12.5, 25, 50 mg/kg Route of Administration: intraperitoneal; one time/day for 31 days Experimental Results: Demonstrated It has anti-tumor effects in vivo and Dramatically delays tumor growth. 25 mg/kg Dramatically diminished tumor weight in mice. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~201.80 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 5 mg/mL (10.09 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 50.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
