Deuruxolitinib, sold under the brand name Leqselvi, is a medication used for the treatment of alopecia areata.[1] It is a Janus kinase inhibitor selective for JAK1 and JAK2.[2] Although the relative effectiveness of deuruxolitinib and another Janus kinase inhibitor—baricitinib—for alopecia areata may vary depending on the population studied, both drugs are more effective than alternative treatments.[3]

Deuruxolitinib was approved for medical use in the United States in July 2024.[1][4]

Medical uses

Deuruxolitinib is indicated for the treatment of adults with severe alopecia areata.[1]

Side effects

The FDA prescribing label for deuruxolitinib contains a boxed warning for serious infections; malignancies; cardiovascular death, myocardial infarction, and stroke; and thrombosis.[5]

Names

Deuruxolitinib is the international nonproprietary name[6] and the United States Adopted Name.[7]

Example 1

Synthesis of Compound 10

      The synthesis of Compound 10, or a pharmaceutically acceptable salt thereof (such as the phosphate salt) may be readily achieved, e.g., reaction of CTP-543 under conditions suitable to provide hydrolysis of the nitrile functionality of CTP-543. CTP-543 can be prepared, e.g., according to the methods described in U.S. Pat. No. 9,249,149 and US Patent Pub. No. 2019/0160068 (the teachings of which are incorporated herein by reference), to produce CTP-543 and/or its phosphate salt. CTP-543 phosphate salt may be transformed into Compound 10 or its phosphate salt according to Scheme 1 below.
      
      To a round bottom flask, equipped with a magnetic stir bar, was charged sulfuric acid (2 mL) followed by careful addition of CTP-543 Phosphate (4.05 g, 9.8 mmol). To the mixture was added another portion of sulfuric acid (2 mL) and water (0.8 mL). The reaction was stirred at room temperature for 4 hours, then quenched by addition of a potassium carbonate solution (80 g, 30% w/w). The product was extracted using isopropyl alcohol. The organic phase was concentrated under vacuum to dryness. The product was dissolved in isopropyl alcohol (100 mL) and phosphoric acid (1 mL, 85% w/w) was added to crystallize the product as the phosphate salt. The precipitate was filtered and dried in a vacuum oven (5 torr, room temp, slight nitrogen purge) to yield the desired compound as an off-white solid (1.82 g, 4.2 mmol, 43% yield). The product was analyzed by HPLC, HRMS, and NMR.
       1H-NMR (400 MHz, DMSO-d 6): δ 12.05 (s, 1H), 8.64 (s, 1H), 8.56 (d, J=0.9 Hz, 1H), 8.26 (s, 1H), 7.55 (dd, J=3.6, 2.3 Hz, 1H), 7.33 (s, 1H), 6.96 (dd, J=3.6, 1.6 Hz, 1H), 6.76 (s, 1H), 4.57 (td, J=9.7, 4.0 Hz, 1H), 2.88 (dd, J=15.3, 10.0 Hz, 1H), 2.64 (dd, J=15.3, 4.0 Hz, 1H), 2.32 (d, J=9.3 Hz, 1H).
      HPLC method summary: column=Waters XBridge C18, 4.6×150 mm, 3.5 μm column; gradient elution: mobile phase A=10 mM ammonium formate, pH 3.9; mobile phase B=acetonitrile; detection=ultraviolet absorbance at 254 nm. Result: Compound (I)=98.7 area %; retention time=11.1 min.
      HRMS: Agilent 6530 Q-TOF LC/MS system with electrospray ionization in positive mode. The measured time-of-flight mass-to-charge ratio (m/z) is 333.22839 (theoretical value=333.22735).
