摘要:
The present invention provides a new bioactive compound of formula (I), which has an antimicrobial activity against pathogenic microorganisms, and a process for production thereof. Also provided are a pharmaceutical composition comprising the compound and pharmaceutically acceptable carrier, a use of the WF002 as a medicament and use of the compound for manufacture of the medicament for treatment of infectious disease.
摘要:
The invention relates to new polypeptide compounds represented by formula (I), wherein R1 is hydrogen, etc., R2 is hydrogen, etc., R3 is hydrogen, etc., and R4 is hydrogen, etc., or a salt thereof which have antimicrobial activities (especially antifungal activities), inhibitory activity on β-1,3-glucan synthase, to process for preparation thereof, to a pharmaceutical composition comprising the same, and to a method for the prophylactic and/or therapeutic treatment of infectious diseases including Pneumocystis carinii infection (e.g. Pneumocystis carinii pneumonia in a human being or an animal.
摘要:
Substances WB2663A, WB2663B and WB2663C are produced by culturing a WB2663-producing bacterium belonging to the genus Pseudomonas to form physiologically active substances and isolating therefrom neutral substances respectively having the following specific rotation: [α]²³ = -36° (C =0.5 in CH₂Cl₂),[α]²³ = -12° (C =0.5 in CH₂Cl₂), and [α]²³ = -9° (C =0.5 in CH₂Cl₂). They have each an excellent antitumor activity.

摘要:
The present invention provides a new antimicrobial compound WF14573, and a process for producing WF14573 by (a) culturing a WF14573 A and/or B-producing microorganism in a nutrient medium and recovering WF14573 A and/or B from the resultant cultured broth or (b) deacylating WF14573 A and/or B in the presence of a microbial substance which is capable of deacylating WF14573 A and/or B. Also provided are an antimicrobial agent comprising WF14573 and carrier(s), a pharmaceutical composition comprising an effective amount of WF14573 and pharmaceutically acceptable carrier(s), a method for killing microorganisms by applying WF14573 to the microoganisms, and use of WF14573 for the treatment of infectious diseases caused by pathogenic microoganisms.

Substances WB2663A, WB2663B and WB2663C are produced by culturing a WB2663-producing bacterium belonging to the genus Pseudomonas to form physiologically active substances and isolating therefrom neutral substances respectively having the following specific rotation: [ alpha ] = -36 DEG (C =0.5 in CH2Cl2),[ alpha ] = -12 DEG (C =0.5 in CH2Cl2), and [ alpha ] = -9 DEG (C =0.5 in CH2Cl2). They have each an excellent antitumor activity.
