Apexbio Technology LLC Tofacitinib (CP-690550) Citrate(Synonyms: Xeljanz, CP-690550 citrate, Tofacitinib citrate, Tasocitinib citrate, CP690550-10 citrate), 50mg, CAS: 540737-29-9.
Tofacitinib citrate (CP-690550 citrate CAS 540737-29-9) is an inhibitor of Janus kinase 3 (JAK3) a hematopoietic cell-restricted tyrosine kinase that regulates lymphocyte proliferation differentiation survival and apoptosis via intracellular signaling pathways It selectively inhibits JAK3 with an IC50 of approximately 1 nM exhibiting weaker inhibitory activity towards JAK2 and JAK1 (approximately 20-fold and 100-fold weaker respectively) Recent binding affinity studies indicate Ki values of 1 6 nM 21 7 nM and 6 5 nM for JAK1 JAK2 and JAK3 respectively Tofacitinib is widely explored in biomedical research involving immune regulation and inflammatory disorders
Apexbio Technology LLC Lapatinib(Synonyms: Tykerb, GW572016, Lapatinib ditosylate, GW-572016, Tyverb), 50mg, CAS: 231277-92-2.
Lapatinib (CAS 231277-92-2) also known as GW572016 is a reversible small-molecule inhibitor targeting epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER-2) By competitively binding to the ATP-binding domain of these receptor tyrosine kinases Lapatinib reduces receptor autophosphorylation subsequently blocking downstream signaling pathways involved in cell survival and proliferation In biochemical kinase assays it exhibits inhibitory activity against recombinant EGFR and HER-2 with IC50 values of 10 8 nmol/L and 9 3 nmol/L respectively Lapatinib is employed in biomedical oncology research investigating targeted inhibition strategies in EGFR- and HER-2-associated cancers
