ABSTRACT
As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.
ABSTRACT
Cancer, also known as malignant tumor, is the second largest disease after heart disease, which is characterized by genomic instability and mutagenicity. Ataxia telangiectasia and RAD3-related kinase (ATR) are members of phosphatidylinositol 3-kinase (PIKK) family, belonging to serine/threonine kinase, one of the key kinases in DNA damage response (DDR) and DNA repair pathway. This paper reviews the latest progress in the ATR inhibitor field including mechanism of action (MOA), therapeutic applications, and the combination therapy from the perspective of medicinal chemistry. It also discusses the possible challenges and future directions of developing ATR inhibitor antitumor drugs, which could provide the scientists in this field the convenience for access the information and application guidance for clinical studies.
ABSTRACT
Random amplified microsatellite polymorphism (RAMP) markers were used to access the genetic diversity among 112 samples of nine populations of Dendrobium officinale Kimura et Migo. Using 16 informative primers, 123 bands were amplified and 86 (69.92%) were polymorphic. The polymorphic bands from three to eight could be detected for each RAMP primer, with a mean of 5, indicating abundant genetic diversity among populations. Genetic similarity coefficients ranged from 0.250 to 0.813. UPGMA dendrogram illustrated 9 populations clustered into 3 groups, and the cluster pattern showed correlation with the locations of the D. officinale populations. These results were supported by the previous conclusions that were achieved by other molecular markers, and RAMP is proved to be effective for evaluating the genetic diversity of wild populations of Dendrobium officinale.
