IPN-60090 dihydrochloride 是一种具有口服活性和高选择性的谷氨酰胺酶 1GLS1的抑制剂 (IC50=31 nM),对 GLS-2 无活性。IPN-60090 dihydrochloride 在体内表现出优良的物理化学和药代动力学特性。IPN-60090 dihydrochloride 可用于实体肿瘤的研究,如肺癌和卵巢癌。
生物活性 | IPN-60090 dihydrochloride is an orally active and highly selective inhibitor ofglutaminase1 (GLS1;IC50=31 nM), with no activity observed against GLS-2. IPN-60090 dihydrochloride exhibits excellent physicochemical and pharmacokinetic propertiesin vivo. IPN-60090 dihydrochloride can be used for solid tumors research, such as lung and ovarian cancers[1][2]. |
IC50& Target | |
体外研究 (In Vitro) | There are two known isoforms of glutaminase: GLS-1 (also called kidney-type or KGA), and GLS-2 (also called liver-type or LGA). GLS-1 is ubiquitous and GLS-2 expression appears limited primarily to the liver. In a dual-coupled enzyme assay, IPN60090 dihydrochloride inhibits purified recombinant human GLS-1 (GAC isoform) with an IC50of 31 nM, and has no activity against GLS-2, with an IC50of >50000 nM[2]. IPN60090 dihydrochloride inhibits the proliferation of A549 cells with an IC50of 26 nM[2].

体内研究 (In Vivo) | IPN60090 dihydrochloride (3 mg/kg for i.v.; 10 mg/kg for p.o.) has excellent pharmacokinetic properties, with CL=4.1 mL/min/kg, t1/2=1 hour, Cmax=19 μM, F%=89%[2]. IPN-60090 dihydrochloride (oral administration; 100 mg/kg; twice daily; 30 days) shows similar efficacy and target engagement to CB-839 (HY-12248) dosed orally at 250 mg/kg twice daily. And the 100 mg/kg BID dose of IPN-60090 is a tolerated dose for the following model study[2].IPN-60090 dihydrochloride (oral administration; 100 mg/kg; twice daily; 30 days; monotherapy or in combination with TAK228 (HY-13328)) causes tumor growth inhibition. IPN-60090 alone demonstrates robust in vivo target engagement in a dose-dependent manner. The glutamate/glutamine ratios and the free plasma concentrations of IPN-60090 at 4 hours post-dose on both day 4 and day 28 are all decreased[2]. Furthermore, IPN-60090 dihydrochloride in combination with TAK228 strongly causes an 85% tumor growth inhibition, IPN-60090 alone causes a 28% tumor growth inhibition in vivo[2].
Animal Model: | Female CD-1 mice[2] | Dosage: | 3 mg/kg for i.v.; 10 mg/kg for p.o. (Pharmacokinetic Analysis) | Administration: | Intravenous injection and oral administration | Result: | CL (4.1 mL/min/kg), t1/2(1 hour) for i.v.; Cmax(19 μM), F% (89%) for p.o.. |
Animal Model: | Ru337 non-small cell lung cancer patient-derived xenograft (PDX) subcutaneous mouse model as monotherapy or in combination[2] | Dosage: | 100 mg/kg | Administration: | Oral administration; 100 mg/kg; twice daily; 30 days; monotherapy or in combination with TAK228 | Result: | Exhibited an improvement in the combination regimen group over either single agent. |
