Oritinib (SH-1028), an irreversible third-generation EGFR TKI, overcomes T790M-mediated resistance in non-small cell lung cancer. Oritinib (SH-1028), a mutant-selective inhibitor of EGFR kinase activity, inhibits EGFR^WT, EGFR^L858R, EGFR^L861Q, EGFR^L858R/T790M, EGFR^d746-750 and EGFR^{d746-750/T790M} kinases, with IC₅₀s of 18, 0.7, 4, 0.1, 1.4 and 0.89 nM, respectively.

In Vitro

Oritinib (SH-1028) binds irreversibly to EGFR kinase by targeting cysteine-797 residue in the ATP binding site via covalent bond formation^[1].
Oritinib (0.001-10 μM) potently and selectively targets mutant EGFR cell lines in vitro^[1].
Oritinib (0.1 μM) continuously inhibits the phosphorylation of EGFR in PC-9 and NCI-H1975 cells at lower concentrations or even drug-free for at least 6 h^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Proliferation Assay^[1]

Cell Line:

A431 (EGFR^WT), H3255 (EGFR^L858R), PC-9 (EGFR^d746-750) and NCI-H1975 (EGFR^L858R/T790M) cells
Concentration:

0.001, 0.01, 0.1, 1, and 10 μM
Incubation Time:

72 hours
Result:

Selectively inhibited EGFR-mutated NCI-H1975, H3255 and PC-9 cells, with IC₅₀s of 3.93±1.12, 9.39±0.88 and 7.63±0.18 nmol/L, respectively, which were about 198-, 83- and 102-fold more sensitive than the inhibition of wild-type EGFR in A431 cells (IC₅₀=778.89±134.74 nM).

In Vivo

Oral administration of Oritinib at a daily dose of 5 mg/kg significantly inhibits proliferation of tumor cells with EGFR sensitive mutation (exon 19 del) and resistant mutation (T790 M) for consecutive 14 days, with no TKI-induced weight loss in mouse xenograft models^[1].
Oritinib shows good bioavailability, and is distributed extensively from the plasma to the tissues^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

6-8 weeks old female mice bearing NCI-H1975 and A431 xenograft models ^[1]
Dosage:

2.5, 5, and 15 mg/kg
Administration:

Orally administrated once daily for consecutive 14 days
Result:

Led to a significant inhibition of tumor cell growth in both PC-9 (exon 19 del) and NCI-H1975 (L858R/T790M) xenograft models.

Animal Model:

NCI-H1975 tumor-bearing mice^[1]
Dosage:

2.5, 5, and 15 mg/kg (Pharmacokinetic Analysis)
Administration:

Oral administration for 1 day or 14 consecutive days.
Result:

The T_max is 1.5-2 h, indicating rapidly distributed into tissues, including lung tumor tissues.
The AUC_0–t values in plasma were 118, 300 and 931 ng×h/mL on Day 1, while 272, 308 and 993 ng×h/ml on Day 14, respectively.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
