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- 2H -isoindol-2-yl) piperidine-2,6-dione The empirical formula for lenalidomide is C 13 H 13 N 3 O 3 , and the gram molecular weight is 259.3. Lenalidomide is a white to slight yellow crystalline powder. It is soluble in organic solvent/water mixtures, and buffered aqueous solvents. Lenalidomide is more soluble in organic solvents and low pH solutions. Solubility was significantly lower in less acidic buffers, ranging from about 0.4 to 0.5 mg/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 capsules are available in 2.5 mg, 5 mg, 10 mg, 15 mg, 20 mg and 25 mg capsules for oral administration. Each capsule contains lenalidomide as the active ingredient and the following inactive ingredients: lactose anhydrous, microcrystalline cellulose, croscarmellose sodium, and magnesium stearate. The 2.5 mg capsule shell contains gelatin, FD&C blue #1, yellow iron oxide, titanium dioxide and black ink. The 5 mg and 25 mg capsule shell contains gelatin, titanium dioxide and black ink. The 10 mg capsule shell contains gelatin, FD&C blue #1, FD&C yellow #6, red iron oxide, yellow iron oxide, titanium dioxide and black ink. The 15 mg capsule shell contains gelatin, FD&C blue #1, titanium dioxide and black ink. The 20 mg capsule shell contains gelatin, FD&C blue #1, yellow iron oxide, titanium dioxide and black ink. The black ink contains dewaxed shellac, black iron oxide and potassium hydroxide. Structure
