Synthesis, Antibacterial Activity and Cytotoxicity of Novel Janus Peptide Dendrimers

Abstract

In an attempt to find new antibacterial agents, a series of well-defined Janus peptide dendrimers, which feature multiple anionic groups and amphiphilic structure, were synthesized and characterized in detail. The antibacterial activities of all the synthesized dendrimers were tested and screened by using the two-fold serial dilution method. Several compounds showed activity against E. coli, S. aureus, methicillin-resistant S. aureus, and E. faecalis. Further cytotoxicity assays showed that the antibacterial dendrimers were nontoxic against HEK293.

Key words

Janus dendrimer - peptide dendrimer - amphiphilic - antibiotics - antibacterial activity

• 19 Synthesis of Janus Dendrimers; Typical Procedure for 2a: Compound 7 (313 mg, 0.5 mmol) dissolved in anhyd THF (25 mL) was cooled to –15 °C, and NMM (10 mmol) and IBCF (10 mmol) were added. After stirring for 10 min, 4a (900 mg, 0.5 mmol) dissolved in anhyd THF (10 mL) was added dropwise. The reaction mixture was vigorously stirred at r.t. for 24 h, then the solution was concentrated under vacuum, and the residue was taken up in EtOAc (30 mL) and washed with 1 M HCl (10 mL), 1 M NaHCO₃ (10 mL), and brine (10 mL). The organic layer was dried over anhyd Na₂SO₄. After concentration, the residue was purified by silica gel column chromatography (CH₂Cl₂–MeOH) to obtain a white waxy solid. Pd/C (10%, 100 mg) was added to a solution of the obtained white waxy solid in MeOH–CH₂Cl₂ (30 mL, 3:1 v/v). The reaction mixture was stirred under a hydrogen atmosphere for 24 h, filtered through a membrane filter, and concentrated under reduced pressure to afford 2a (539 mg, 64%) as a white foam. ¹H NMR (400 MHz, DMSO-d ₆): δ = 0.83–0.87 (t, J = 6.4 Hz, 6 H, 2 × CH₃), 1.23 (br s, 40 H, myristic acid 20 × CH₂), 1.48–1.49 (m, 4 H, myristic acid-β-CH ₂ × 2), 2.24–2.35 (m, 8 H, myristic acid-α-CH ₂ × 2 + Asp-β-CH ₂/2 × 4), 2.38–2.59 (m, 16 H, succinic acid CH ₂ × 2 + NCH₂CH ₂CONH × 6), 2.63–2.70 (m, 4 H, Asp-β-CH ₂/2 × 4), 3.41–3.60 (m, 16 H, NCH ₂CH₂O × 3 + NCH ₂CH₂CONH × 3), 3.99 (br s, 6 H, Gly-CH ₂ × 3), 4.05–4.18 (m, 4 H, NCH₂CH ₂O × 2), 4.48–4.54 (m, 4 H, Asp-α-CH × 4), 7.89 (br s, 1 H, CONH), 7.96 (br s, 1 H, CONH), 8.10 (br s, 1 H, CONH), 8.25 (br s, 1 H, CONH), 8.27 (br s, 1 H, CONH), 8.39 (br s, 1 H, CONH), 8.41 (br s, 1 H, CONH), 12.64 (br s, 8 H, Asp-COOH × 8).
