The MICs of WSKK11 against Staphylococcus epidermidis, Staphylococcus aureus and Candida albicans were 8, 8 and 32 mg\/L, while those of WSRR11 were 64, 32 and 32 mg\/L, respectively. WSKK11 and WSRR11 were less toxic to human erythrocytes (&amp;lt;2%) and not toxic to macrophages, keratinocytes and fibroblasts up to 512 mg\/L. WSKK11 and WSRR11 mostly revealed the conformation of the undefined or random coil structures under mimicked environmental conditions. The peptides affected cell surfaces and cell membranes of C. acnes as well as possibly translocating through the cell membrane, observed by a combination of SEM and TEM, respectively. WSKK11 and WSRR11 had the ability to bind bacterial DNA.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>The two novel antimicrobial peptides WSKK11 and WSRR11 are members of a new class of antimicrobial agents that could deal with acne problems.
