• Antimicrobial activity, biocompatibility and hydrogelation ability of dipeptide-based amphiphiles
  作者：Rajendra Narayan Mitra、Anshupriya Shome、Pritha Paul、Prasanta Kumar Das

  DOI：10.1039/b815368j

  日期：——

  The development of new antibiotics is of increasing importance due to the growing resistance power of microbes against conventional drugs. To this end, cationic peptides are emerging as clinically potent antimicrobial agents. In the present study, we have synthesized six dipeptide-based cationic amphiphiles with different head group structures by varying combinations of L-amino acid residues. These amphiphiles showed remarkable growth inhibiting activity on several Gram-positive (minimum inhibitory concentration (MIC) = 0.1–10 µg/mL) and Gram-negative (MIC = 5–150 µg/mL) bacteria as well as on fungus (MIC = 1–50 µg/mL). The inherent antimicrobial efficacies of these cationic dipeptides were influenced by the head group architecture of the amphiphiles. Encouragingly, these amphiphiles selectively attacked microbial cells, while showing biocompatibility toward mammalian cells. The results show that the rational designing of short peptide-based cationic amphiphiles might serve as a promising strategy in the development of antimicrobial agents with greater cell specificities. In addition, the amphiphiles showed water gelation ability at room temperature. The formation of non-covalent supramolecular networks in gelation was established by microscopic and spectroscopic studies.

  由于微生物对传统药物的耐药能力不断增强，新型抗生素的研发日益重要。为此，阳离子肽作为一种临床有效的抗菌剂正在崭露头角。在本项研究中，我们通过改变L-氨基酸残基的组合，合成了六种具有不同头部结构的双肽基阳离子两亲性分子。这些两亲性分子对多种革兰氏阳性菌（最低抑制浓度（MIC）= 0.1–10 µg/mL）、革兰氏阴性菌（MIC = 5–150 µg/mL）以及真菌（MIC = 1–50 µg/mL）显示出显著的生长抑制活性。这些阳离子双肽的固有抗菌功效受到两亲性分子头部结构的影响。令人鼓舞的是，这些两亲性分子选择性地攻击微生物细胞，同时对哺乳动物细胞表现出生物相容性。结果表明，合理设计基于短肽的阳离子两亲性分子可能是开发具有更高细胞选择性的抗菌剂的潜在策略。此外，这些两亲性分子在室温下具有水凝胶化能力。通过显微镜和光谱学研究，建立了凝胶化中非共价超分子网络的形成。
• Carbonic anhydrase activators: amino acyl/dipeptidyl histamine derivatives bind with high affinity to isozymes I, II and IV and act as efficient activators

  a series of compounds with the general formula AA-Hst (AA = amino acyl; dipeptidyl). The new derivatives were assayed as activators of three carbonic anhydrase (CA) isozymes, hCA I, hCA II (cytosolic forms) and bCA IV (membrane-bound form). Efficient activation was observed against all three isozymes, but especially against hCA I and bCA IV, with affinities in the nanomolar range for the best compounds
