You can buy Selinex at the lowest price at Nextgen.ooo online pharmacy. Selinexor is a first-in-class selective inhibitor of nuclear transport (SINE). Selinexor in combination with bortezomib and dexamethasone is currently approved for the treatment of multiple myeloma, a type of cancer that forms from antibody-producing plasma cells. This condition is typically treated with high-dose bortezomib and dexamethasone chemotherapy followed by an autologous stem cell transplant. Other chemotherapy for multiple myeloma includes lenalidomide and dexamethasone, thalidomide, and may include melphalan if the patient is not eligible for a transplant. Selinexor also received accelerated approval for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma who have received at least 2 lines of systemic therapyz.
 
Selinexor binds to and inhibits exportin 1 (XPO1). XPO1 is a nuclear exporter protein that contains a pocket to which nuclear proteins can bind. When complexed with these proteins and Ran, activated by guanosine triphosphate (GTP) binding, the XPO1-protein-Ran-GTP complex is able to exit the nucleus through a nuclear pore. Once outside, the GTP is hydrolyzed and the complex dissociates. Inhibition of this process in cancer cells allows XPO1 targets, many of which are tumor suppressors, to assemble in the nucleus, leading to increased transcription of tumor suppressor genes. Tumor suppressor proteins known to be affected by XPO1 inhibition include p53, p73, adenomatous polyposis coli, retinoblastoma, forkhead box protein O, breast cancer 1, nucleophosmin, and merlin. Regulators of cell cycle progression are also affected, namely p21, p27, galectin-3, and Tob. NFκB inhibitor also accumulates in the nucleus, resulting in decreased activity of NFκB, a known cancer-promoting factor. XPO1 is involved in the formation of a complex with eukaryotic initiation factor 4E and promotes messenger RNA transport for several genes, including the cell cycle promoters cyclin D1, cyclin E, and CDK2/4/6, as well as the anti-apoptotic proteins Mcl-1 and Bcl-xL. These large-scale changes in protein expression and gene transcription culminate in cell cycle arrest and promotion of apoptosis in cancer cells.
