Highly Efficient and Optically Active Synthesis of bis-THF Ligand of Darunavir
An inexpensive and easily scalable method utilizing optically active sugars increases the efficiency and purity of bis-THF synthesis, a key component in the manufacture of the HIV-1 drug Darunavir.
Researchers at Purdue University have developed an efficient method to synthesize an optically pure sub-unit bis-THF, a key structure for producing the HIV-1 drug Darunavir. Darunavir is the most recent FDA approved HIV-1 protease inhibitor drug for the treatment of patients with HIV-1 infection and AIDS. It is potent against highly multidrug resistant HIV-1 variants and has become the front-line therapy for the treatment of HIV/ AIDS. Current methods of Darunavir synthesis often involve numerous complex steps and the resulting bis-THF may not be optically pure. Further, these methods frequently have high cost associated with the starting materials and reagents and the synthesis time is often lengthy.
Researchers at Purdue University have developed a method that uses optically active sugars to synthesize optically pure bis-THF. This inexpensive and efficient method is beneficial for scaling up the synthesis of Darunavir.
