  Synthesis, structure–activity relationships, and mechanism of action of anti-HIV-1 lamellarin α 20-sulfate analogues

  摘要：

  Lamellarin a and six different types of lamellarin alpha 20-sulfate analogues were synthesized and their structure-activity relationships were investigated using a single round HIV-1 vector infection assay. All lamellarin sulfates having pentacyclic lamellarin core exhibited anti-HIV-1 activity at a 10 mu M concentration range regardless of the number and position of the sulfate group. On the other hand, non-sulfated lamellarin alpha and ring-opened lamellarin sulfate analogues did not affect HIV-1 vector infection in similar concentrations. The lamellarin sulfates utilized in this study did not exhibit unfavorable cytotoxic effect under the concentrations tested (IC50 > 100 mu M). Confocal laser scanning microscopic analysis indicated that hydrophilic lamellarin sulfates were hardly incorporated in the cell. HIV-1 Env-mediated cell-cell fusion was suppressed by lamellarin sulfates. These results suggested that lamellarin sulfates have a novel anti-HIV-1 activity besides the previously reported integrase activity inhibition, possibly at a viral entry step of HIV-1 replication.

• Divergent Synthesis of Lamellarin α 13-Sulfate, 20-Sulfate, and 13,20-Disulfate
  作者：Masatomo Iwao、Tsutomu Fukuda、Sho Saeki、Takeshi Ohta

  DOI：10.3987/com-09-s(s)100

  日期：——

  A divergent synthesis of three sulfate derivatives of lamellarin alpha, namely, lamellarin alpha 13-sulfate (2), 20-sulfate (1), and 13,20-disulfate (4) has been achieved via a common intermediate (6) in which 13-OH and 20-OH of the lamellarin core are differentially protected by MOM and benzyl groups, respectively. Compound (6) in turn was prepared using sequential Suzuki-Miyaura coupling of 3,4-dihydroxypyrrole bistriflate (7) as a key reaction.
