The present invention relates to the use of known and novel naphthoquinones in the treatment and prophylaxis of Pneumocystis carinii infections, and for the manufacture of medicaments for the treatment and prophylaxis of P.carinii infections, novel formulations containing said compounds, and novel naphthoquinones of formula (VI):
wherein
R¹¹ and R¹² each represent =O and the dotted line represents a double bond between the 2 and 3 positions of the quinone ring, in which case R¹³ represents a group -OCOR⁵; a group OR⁶ or SR⁶; or a group NR⁷R⁸; or the dotted line represents double bonds at the 1,2 and 3,4 positions of the quinol ring and R¹¹, R¹² and R¹³ each represents a group -OCOR¹⁴, wherein R¹⁴ represents an optionally substituted C₁₋₁₀alkyl group.
本发明涉及已知和新型萘醌在治疗和预防卡氏肺孢子虫感染中的用途,以及用于制造治疗和预防卡氏肺孢子虫感染的药物、含有上述化合物的新型制剂和式(VI)的新型萘醌:
其中
R¹¹ 和 R¹² 各自代表 =O,虚线代表醌环 2 和 3 位之间的双键,在这种情况下,R¹³ 代表基团 -OCOR⁵;基团 OR⁶ 或 SR⁶;或基团 NR⁷R⁸;或虚线代表喹啉环 1、2 和 3、4 位上的双键,且 R¹¹、R¹² 和 R¹³ 各代表一个基团 -OCOR¹⁴,其中 R¹⁴ 代表任选取代的 C₁₋₁₀烷基。
