- Description
- Universal access to antiretroviral drugs is still a challenge in developing nations. This promoted an investigation into an efficient process towards the synthesis of zidovudine (AZT), a nucleoside reverse transcriptase inhibitor (NRTI) that is used to treat HIV/AIDS. It was the first antiretroviral drug approved by the FDA and it is still widely used today. AZT works by blocking the enzyme reverse transcriptase, which is used by HIV to copy its genetic material. This prevents HIV from replicating and spreading throughout the body. AZT is usually taken in combination with other antiretroviral drugs. AZT was originally used as a single-drug therapy, but it is no longer recommended for this purpose as HIV can become resistant to AZT if it is used alone. Consequently, AZT is most commonly used as part of a combination therapy; this means that it is taken with other antiretroviral drugs. This helps to prevent HIV from becoming resistant to AZT. AZT can be used to prevent mother-to-child transmission of HIV; it is usually given to HIV-positive women during pregnancy and childbirth. AZT can also be used to treat post-exposure prophylaxis (PEP); this is a course of antiretroviral drugs that is taken after a possible exposure to HIV. The application of continuous flow microreactors to reaction chemistries, such as this, could provide a potentially practical solution that could be used to meet the rising needs for antiretroviral drugs in Africa and to give new opportunities for efficient local drug manufacture. Consequently, the focus of this research was to develop safe and efficient processes towards AZT by taking advantage of micro reactor technology. Furthermore, since there is no literature on continuous flow synthesis of this drug, this research extensively unearthed interesting continuous flow processes towards zidovudine.
