E2459 Ginsenoside Rg5 Ginsenoside Rg5, the main component of Red ginseng, blocks binding of IGF-1 to its receptor with an IC50 of ~90 nM. This compound also inhibits the mRNA expression of COX-2 via suppression of the DNA binding activities of NF-κB p65.
E3106 Dioscoreae Nipponicae Rhizoma Extract Dioscoreae Nipponicae Rhizoma Extract is extracted from the rhizome of Dioscorea nipponica, of which the main component decreases the phosphorylation in IGF-1R, which in turn inhibits the phosphorylation and activation of PI3K-AKT and Rap1-MEK signalling pathways, promoting cell apoptosis and Graves’ disease remission.
E0794 MID-1 MID-1 is a disruptor of MG53-IRS-1 (Mitsugumin 53-insulin receptor substrate-1) interaction, which can disrupt molecular association of MG53 with IRS-1 and abolish MG53-induced IRS-1 ubiquitination and degradation in skeletal muscle, leading to elevated IRS-1 expression level and increased insulin signalling and glucose uptake.
S7453 MSDC-0160 MSDC-0160 (CAY10415) is a prototype mTOT-modulating insulin sensitiser being studied to treat diabetes and Alzheimer's disease. Phase 2.
E0939 Insulin Degludec Insulin Degludec is an acylated basal insulin with a unique mechanism of protracted absorption involving the formation of a depot of soluble multihexamer chains after subcutaneous injection, shows a very long duration of action, with a half-life exceeding 25 h in PK/PD studies.
S6443 Chromium picolinate Chromium picolinate is a coordination complex consisting of chromium(III) and picolinic acid. It is used as a nutritional supplement for optimal insulin function in patients with Type 2 diabetes or promotion of weight loss.
S3187 SBI-477 SBI-477 is an insulin signaling inhibitor that deactivates the transcription factor MondoA, leading to reduced expression of the insulin pathway suppressors thioredoxin-interacting protein (TXNIP) and arrestin domain-containing 4 (ARRDC4). This compound inhibits triacylglyceride (TAG) synthesis and enhances basal glucose uptake in human skeletal myocytes.
S7083 Ceritinib Ceritinib is a potent inhibitor against ALK with an IC50 of 0.2 nM in cell-free assays. This compound also inhibits IGF-1R, InsR, STK22D and FLT3 with IC50 of 8 nM, 7 nM, 23 nM and 60 nM, respectively. Phase 3.

S1069 Luminespib (NVP-AUY922) Luminespib (AUY-922, NVP-AUY922, VER-52296) is a highly potent HSP90 inhibitor for HSP90 R / R with IC50 of 13 nM /21 nM in cell-free assays, exhibits weaker potency against the HSP90 family members GRP94 and TRAP-1, and demonstrates the tightest binding of any small-molecule HSP90 ligand. It effectively downregulates and destabilizes the IGF-1R R protein, resulting in growth inhibition, autophagy and apoptosis. Phase 2.
