Citreamicin alpha（LL-E 19085-alpha）是一种抗生素，通过琼脂稀释法已测试其对429株临床分离的革兰氏阳性球菌的体外抗菌活性，包括313株葡萄球菌和116株链球菌。该抗生素的体外活性与氨苄西林、阿莫西林、头孢噻吩、红霉素和万古霉素进行了比较。对葡萄球菌而言，Citreamicin alpha的MIC值在0.12-4.0 μg/ml范围内，而对Streptococcus pyogenes的MIC为0.03-0.12 μg/ml。肠球菌较为耐药，64%的测试株需要2.0 μg/ml的药物才能抑制。其抗菌活性显著优于氨苄西林、阿莫西林、头孢噻吩和红霉素，与万古霉素相当或略逊。
