Cat.No. 5811 - NBD 556 | C17H24ClN3O2 | CAS No. 333353-44-9
Description: Blocks HIV-1 viral cell entry; CD4 mimetic
Chemical Name: N1-(4-Chlorophenyl)-N2-(2,2,6,6-tetramethyl-4-piperidinyl)ethanediamide
Purity: ≥98% (HPLC)

Biological Activity

CD4 mimetic (IC50 values are in low micromolar range, dependent on cell type and HIV strain). Recognizes and induces structural changes in HIV-1 envelope protein gp120, analogous to CD4 binding. Inhibits HIV-1 cell entry in CXCR4 and CCR5 expressing cell lines, by blocking virus-cell and cell-cell fusion.

Preparing Stock Solutions

The following data is based on the product molecular weight 337.84. Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 2.96 mL 14.8 mL 29.6 mL
5 mM 0.59 mL 2.96 mL 5.92 mL
10 mM 0.3 mL 1.48 mL 2.96 mL
50 mM 0.06 mL 0.3 mL 0.59 mL
