Application

Reactant for preparation of:
  • Organosilane amines as potent inhibitors and structural probes of influenza A virus M2 proton channel
  • Lamellarin D analogues as inibitors of topoisomerase I and potential antitumor agents
  • Azapeptide tocolytic agents as inhibitors of prostaglandin F2a receptor for preventing preterm labor
  • Thiazolidinones spiro-fused to indolin-2-ones as potent and selective inhibitors of Mycobacterium tuberculosis protein tyrosine phosphatase B
  • Orally bioavailable quinoline-based antidiabetic dipeptidyl peptidase IV inhibitors targeting Lys554
  • Pyrimidine nucleoside derivatives with nitric oxide donors as antiviral agents
  • Benzyladenosine compounds targeting adenosine A2A receptor and adenosine transporter for neuroprotection
  • Naphthol derivatives as inhibitors of the vanilloid receptor TRPV1 with improved potency in rat cystometry models of urinary incontinence
