central analgesic, NB001, NB 001, HTS 09836, J89QT81NBQ

NB-001 has been investigated for the treatment of Recurrent Herpes Labialis.

NB001 (HTS 09836) is an adenylcyclase 1 (AC1) inhibitor which has effect on neural and non-neural pain by modulating AC1 activity

Peturadol (also known by its developmental code NB001) is a potent, selective, and orally active adenylyl cyclase 1 (AC1) inhibitor. It is primarily recognized as a specialized chemical compound used in advanced medical and pharmacological laboratory research.

Because drug names can sometimes look or sound very similar, please check the spelling carefully. If you are looking for a medication prescribed to you by a doctor, it is highly likely you mean Patradol (a combination painkiller containing tramadol and paracetamol) or Pentadol / Tapentadol (an opioid analgesic).

Synthesis and Purification of Intermediate 2

The compound 1 (20.00 g, 111.62 mmol, 1.00 eq) was dissolved in dioxane (600.00 mL), and then SOCl ₂(26.56 g, 223.24 mmol, 16.20 mL, 2.00 eq) was slowly added to the afore-mentioned reaction solution, and the mixture was continuously stirred at 100° C. for 4 hours. The LCMS assay showed the raw materials are reacted completely and the desired product was generated. The solvent in the reaction solution was removed under reduced pressure in a water pump. The gray residue was added into 100 ml of ethanol and stirred for 10 minutes. The mixture was filtered through a sintered glass funnel. 100 ml of saturated sodium carbonate solution was added to the filtered solid and stirred for 20 minutes. The mixture was filtered through a sintered glass funnel. The filtered solid was spin-dried in a water pump under reduced pressure to obtain crude intermediate 2 (19.60 g, 98.59 mmol, with a yield of 88.32% and a purity of 99.4%), and the product is directly used in the next step without further purification.

(2) Synthesis and Purification of NB001

The compound 2 (19.60 g, 99.18 mmol, 1.00 eq) was dissolved in n-BuOH (390.00 mL), and then the compound 3 (30.69 g, 297.54 mmol, 3.00 eq) was slowly added to the afore-mentioned reaction solution, and the mixture was continuously stirred at 110° C. for 18 hours. The LCMS assay showed the raw materials are reacted completely and the desired product was generated. The solvent was removed under reduced pressure through a water pump, and the residue was concentrated to obtain a yellow crude product. 196 ml of DMF was added into the yellow crude product, then the mixture was continuously stirred at −40° C. for 1 hour. Then the mixture was filtered through a sintered glass funnel. 200 ml of ethyl acetate was added into the filtered solid, and the mixture was filtered again to obtain an off-white solid NB001 (19.74 g, 71.38 mmol, with a yield of 71.97% and a purity 95.587%).
