P005672 hydrochloride is a novel, narrow-spectrum tetracycline derivative for the treatment of moderate to severe inflammatory non-nodular acne[1].
In vitro, P005672 hydrochloride (100μM; 25min) reduces Staphylococcus aureus DNA and protein synthesis[2]. P005672 hydrochloride exhibited lower inhibitory activity against microbial species representing human gastrointestinal microbiota compared to minocycline[3].
In vivo, in a rat paw edema model, the anti-inflammatory activity of P005672 hydrochloride (1, 5, 10, 25, 50, 75, 100 and 125mg/kg; 3h; i.p.) was comparable to doxycycline and minocycline[2]. In a murine systemic (intraperitoneal) infection model, P005672 hydrochloride (0.25 mg/kg; 48h; s.c.) was effective in treating the systemic infection caused by Staphylococcus aureus, while P005672 hydrochloride (40 mg/kg; 48h; s.c.) did not demonstrate in vivo efficacy against the systemic infection caused by Escherichia coli PBS1478[4].

体外研究显示,P005672 hydrochloride (100μM; 25min)可减少金黄色葡萄球菌的DNA和蛋白质合成[2]。与米诺环素相比,P005672 hydrochloride (0.016-8µg/mL; 48h)对代表人类胃肠道微生物群的微生物种类显示出更低的抑制活性[3]。
体内研究方面,在大鼠足趾水肿模型中,P005672 hydrochloride (1, 5, 10, 25, 50, 75, 100和125mg/kg; 3小时; 腹腔注射)的抗炎活性与多西环素和米诺环素相当[2]。在小鼠全身(腹腔)感染模型中,P005672 hydrochloride (0.25mg/kg; 48小时; 皮下注射)对由金黄色葡萄球菌引起的全身感染有效,而P005672 hydrochloride (40 mg/kg; 48小时; 皮下注射)未显示出对由大肠杆菌PBS1478引起的全身感染的体内疗效[4]。
