e-101

Entrectinib (RXDX-101) is an inhibitor of TrkA (IC50: 1.7 nM), TrkB (IC50: 0.1 nM), and TrkC (IC50: 0.1 nM), as well as anaplastic lymphoma kinase (ALK; IC50: 1.6 nM) and C-ros oncogene 1 (ROS1; IC50: 0.2 nM). Entrectinib blocks proliferation of ALK-dependent cell lines, including those with C1156Y or L1196M resistance mutations, and inhibits ALK‐dependent signaling. It has been shown to inhibit the growth of a non-small cell lung Y cell line bearing an EML4-ALK rearrangement. In mice bearing various ROS1, Trk, or ALK-driven xenografts, Entrectinib has been shown to induce tumor regression.

Zilovertamab vedotin (VLS-101) is a novel antibody-drug conjugate consisting of the humanized monoclonal antibody zilovertamab linked to the anti-microtubule cytotoxin monomethyl auristatin E (MMAE). Upon binding to ROR1 on tumor cells, zilovertamab vedotin is rapidly internalized and directed to lysosomes where the conjugate undergoes cleavage, releasing MMAE. This process induces apoptosis in the targeted cells. Zilovertamab vedotin has potential applications in cancer research [1].

Riboflavin (E101) is a micronutrient that occurs in the free form only in the retina of the eye, in whey, and in urine; its principal forms in tissues and cells are as flavin mononucleotide and flavin-adenine dinucleotide.
