Anti-Bacterial Agents↗

PubMedDate not supplied

[Antibacterial activity of the derivatives of cholic acid (author's transl)].

The synthesis of derivatives of cholic acid with L-lysine and Lysil-lysine with antibacterial activity, is here described. Derivatives with one molecule of lysine show antibacterial activity at 100 mug/ml concentration, while lysil-lysine derivatives, particularly Col-Lys-Lys-NH2-2HCl, are effective also at 25 mug/ml.

[Antibacterial activity of the derivatives of dehydro-and deoxy-colic acids (author's transl)].

The synthesis of derivatives of dehydro-and deoxy-colic acids with L-lysine and Lysil-lysine with antibacterial activity, is here described. Results show no antibacterial activity of dehydrocolic acid derivatives, while deoxycol-lys-OH-HCl, and particularly deoxycol-lys-NH2-2HCl, seem to be very effective on Gram-positive bacteria at 5 mug/ml, and on Gram-negatives at 25 mug/ml.
