PubMed AbstractThe use of highly active antiretroviral therapy (HAART) has made the human immunodeficiency virus (HIV) a chronic disease rather than a terminal disease. Non-nucleoside reverse transcriptase ...The use of highly active antiretroviral therapy (HAART) has made the human immunodeficiency virus (HIV) a chronic disease rather than a terminal disease. Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are an important component of HAART, although we are seeing clinically relevant drug-resistant mutants such that there is a need to develop new molecules. We recently identified a new class of -phenyl-1-(phenylsulfonyl)-1-1,2,4-triazol-3-amine HIV-1 NNRTI, with one known as compound 12126065, with sub nanomolar (nM) potency in TZM-bl cells (HeLa cells expressing CD4, CCR5, and CXCR4) with no in vivo acute or subacute toxicity. We now describe the cryo-EM structure of this molecule (resolution of 3.53 Å) and compare it to analogues and other known NNRTIs. We also describe the synthesis and activity of five additional analogues of this class of compounds, some of which have promising activity against a K103N/Y181C (A17) double mutant, which will enable the design of future molecules.

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.

Jul 12, 2017. Major update of PDB

Major update of PDB

  • wwPDB released updated PDB data conforming to the new PDBx/mmCIF dictionary.
  • This is a major update changing the version number from 4 to 5, and with Remediation, in which all the entries are updated.
  • In this update, many items about electron microscopy experimental information are reorganized (e.g. em_software).
  • Now, EM Navigator and Yorodumi are based on the updated data.
