A docking model of dapsone bound to HLA-B*13:01 explains the risk of dapsone hypersensitivity syndrome. J Dermatol Sci 2017; 88:320-329. [PMID: 28870516 DOI: 10.1016/j.jdermsci.2017.08.007] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2017] [Revised: 07/04/2017] [Accepted: 08/08/2017] [Indexed: 12/20/2022]
Abstract
BACKGROUND Dapsone (4,4'-diaminodiphenylsulfone) has been widely used for the treatment of infections such as leprosy. Dapsone hypersensitivity syndrome (DHS) is a major side effect, developing in 0.5-3.6% of patients treated with dapsone, and its mortality rate is ∼10%. Recently, human leukocyte antigen (HLA)-B*13:01 was identified as a marker of susceptibility to DHS. OBJECTIVES To investigate why HLA-B*13:01 is responsible for DHS from a structural point of view. METHODS First, we used homology modeling to derive the three-dimensional structures of HLA-B*13:01 (associated with DHS) and HLA-B*13:02 (not so associated despite strong sequence identity [99%] with HLA-B*13:01). Next, we used molecular docking, molecular dynamic simulations, and the molecular mechanics Poisson-Boltzman surface area method, to investigate the interactions of dapsone with HLA-B*13:01 and 13:02. RESULTS We found a crucial structural difference between HLA-B*13:01 and 13:02 in the F-pocket of the antigen-binding site. As Trp95 in the α-domain of HLA-B*13:02 is replaced with the less bulky Ile95 in HLA-B*13:01, we found an additional well-defined sub-pocket within the antigen-binding site of HLA-B*13:01. All three representative docking poses of dapsone against the antigen-binding site of HLA-B*13:01 used this unique sub-pocket, indicating its suitability for binding dapsone. However, HLA-B*13:02 does not seem to possess a binding pocket suitable for binding dapsone. Finally, a binding free energy calculation combined with a molecular dynamics simulation and the molecular mechanics Poisson-Boltzman surface area method indicated that the binding affinity of dapsone for HLA-B*13:01 would be much greater than that for HLA-B*13:02. CONCLUSIONS Our computational results suggest that dapsone would fit within the structure of the antigen-recognition site of HLA-B*13:01. This may change the self-peptides that bind to HLA-B*13:01, explaining why HLA-B*13:01 is a marker of DHS susceptibility.

Yanagisawa M, Sugiya M, Iijima H, Nakagome I, Hirono S, Tsuda T. Genistein and daidzein, typical soy isoflavones, inhibit TNF-α-mediated downregulation of adiponectin expression via different mechanisms in 3T3-L1 adipocytes. Mol Nutr Food Res 2012; 56:1783-93. [PMID: 23109410 DOI: 10.1002/mnfr.201200284] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2012] [Revised: 07/13/2012] [Accepted: 08/22/2012] [Indexed: 12/20/2022]
Abstract
SCOPE Previous reports suggest that soy isoflavones have multiple biological functions and may help to restore adiponectin expression and insulin sensitivity. However, little is known about whether soy isoflavones can inhibit the downregulation of adiponectin and their molecular mechanisms. In the present study, we demonstrate that genistein (Gen) or daidzein (Dai) can significantly inhibit the downregulation of adiponectin expression via unique and different molecular mechanisms. METHODS AND RESULTS Pretreatment with Gen or Dai significantly inhibited the tumor necrosis factor-alpha (TNF-α)-mediated downregulation of adiponectin expression in 3T3-L1 adipocytes. Gen inhibited the TNF-α-induced c-Jun-NH(2) -terminal kinase (JNK) signaling that is involved in adiponectin expression. Molecular docking studies based on JNK1 with Gen or Dai clearly supported our experimental results. However, Dai did not significantly inhibit JNK signaling. Dai did, however, inhibit the TNF-α-induced downregulation of forkhead box-containg protein O1, which is also involved in adiponectin expression. CONCLUSION These data demonstrate that: (i) both Gen and Dai significantly inhibit the TNF-α-mediated downregulation of adiponectin in adipocytes; (ii) Gen is an effective inhibitor of JNK activation, thus inhibiting the TNF-α-mediated downregulation of adiponectin; and (iii) Dai can inhibit the downregulation of adiponectin by restoring the TNF-α-mediated reduction of forkhead box-containg protein O1 protein expression.

Abstract
BACKGROUND Previous reports suggest that Brazilian propolis has multiple biological functions and may help to restore adiponectin expression and insulin sensitivity. However, little is known about the molecular mechanisms by which these compounds inhibit the downregulation of adiponectin. METHODS The effect of various Brazilian propolis-derived components on inhibition of tumor necrosis factor-α (TNF-α)-mediated downregulation of adiponectin expression in 3T3-L1 adipocytes and molecular mechanism was investigated. RESULTS AND CONCLUSIONS Pretreatment with either artepillin C (C3) or its derivative (C4) significantly inhibited TNF-α-mediated downregulation of adiponectin expression in 3T3-L1 adipocytes. Interestingly, C3 strongly activated peroxisome proliferator-activated receptor γ (PPARγ) transcriptional activity. Treatment of adipocytes with C3 resulted in the upregulation of adiponectin and fatty acid-binding protein 4 expression, but C4 did not significantly induce PPARγ transactivation. C4 did, however, inhibit the TNF-α-induced c-Jun-NH(2)-terminal kinase (JNK) signaling that is involved in adiponectin expression. Molecular docking studies based on hPPARγ with C3 and JNK1 with C4 clearly supported our experimental results. These data demonstrate that 1) both C3 and C4 significantly inhibit the TNF-α-mediated downregulation of adiponectin in adipocytes, 2) C3 functions as a PPARγ agonist, and its inhibition of the effect of TNF-α is due to this PPARγ transactivation, and 3) C4 is an effective inhibitor of JNK activation, thus inhibiting the TNF-α-mediated downregulation of adiponectin. GENERAL SIGNIFICANCE Brazilian propolis-derived components (C3 and C4) can significantly inhibit TNF-α-mediated downregulation of adiponectin in adipocytes, although they do so via different mechanisms.
