Lenalidomide, a thalidomide analogue, is an immunomodulatory agent with antiangiogenic and antineoplastic properties. The chemical name is 3-(4-amino-1-oxo 1,3-dihydro-2 H -isoindol-2-yl) piperidine-2,6-dione and it has the following chemical structure: 3-(4-amino-1-oxo 1,3-dihydro-2 H -isoindol-2-yl) piperidine-2,6-dione The empirical formula for lenalidomide is C 13 H 13 N 3 O 3 , and with relative molecular mass 259.26 a.m.u. Lenalidomide is an off-white to pale-yellow solid powder. It is freely soluble in dimethyl formamide and practically insoluble in water, diethyl ether, ethanol and buffered aqueous solvents. Solubility was significantly lower in buffers, ranging from 1.2 to 6.8 as 0.01g in 100 mL. Lenalidomide has an asymmetric carbon atom and can exist as the optically active forms S(-) and R(+), and is produced as a racemic mixture with a net optical rotation of zero. Lenalidomide is available in 2.5 mg capsules for oral administration. Each capsule contains lenalidomide as the active ingredient and the following inactive ingredients: lactose anhydrous, croscarmellose sodium, magnesium stearate, and microcrystalline cellulose. The 2.5 mg capsule shell contains FD&C Blue # 2, gelatin, titanium dioxide, and yellow iron oxide. The imprinting ink of 2.5 mg contains black iron oxide, potassium hydroxide, propylene glycol, shellac, and strong ammonia solution. Image
