艾滋病毒药物发现的新目标(New targets for HIV drug discovery)

Recent estimates suggest close to one million people per year die globally owing to HIV-related illnesses. Therefore, there is still a need to identify new targets to develop future treatments. Many of the more recently identified targets are host-related and these might be more difficult for the virus to develop drug resistance to. In addition, there are virus-related targets (capsid and RNAse H) that have yet to be exploited clinically. Several of the newer targets also address virulence factors, virus latency or target persistence. The targets highlighted in this review could represent the next generation of viable candidates for drug discovery projects as well as continue the search for a cure for this disease.

 Introduction   

AIDS, caused by HIV, was first recognized as a new disease in 1981 and is still one of the most significant pathogens affecting humankind [1]. Numbers published by the WHO are particularly bleak. It has claimed >35 million lives globally, and 940 000 people died of HIV-related illnesses in 2017 alone [2]. Currently, approved HIV drugs target reverse transcriptase (RT), HIV protease and integrase (IN), the C–C motif chemokine receptor type 5 (CCR5) found on the host cells [3], as well as the process of membrane fusion. HIV can be managed, albeit with a cocktail of 2–4 antiretroviral drugs that need to be taken regularly. Side effects are a concern for these drugs that need to be taken for decades now that it is treated as a chronic disease [4]. Also, many patients develop HIV-associated neurological dysfunctions, resulting in a range of cognitive and motor function deficits [5,6]. Virus can remain in the central nervous system (CNS) and replicate, which then results in the neurological disorders. This could be caused by the inability of HIV medications to cross the blood–brain barrier (BBB) [7] and inhibit HIV in the brain, which is crucial to reverse or improve HIVassociated neurocognitive disorder [8,9]. Although it is possible to improve on known classes of drugs such as the RT inhibitors [10], these continuing liabilities of current HIV treatments suggest that it is important to find drugs that can intervene at other targets whether against host or virus. The following represents a selection of predominantly newer promising targets (Table 1) that have already been modulated by small molecules or for which crystal structures are available.
