Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medicines, and relates to acrylamide compounds containing azole structures, a preparation method thereof, and medical uses thereof. Background Art
[0002] Azoles are the first-line drugs for the treatment of invasive fungal infections. They are the most numerous and most widely used in clinical practice. Azoles are cytochrome P450-14α-demethylase (CYP51) inhibitors that prevent the biosynthesis of ergosterol in fungi, leading to changes in cell membrane permeability and thus inhibiting fungal growth. Representative drugs include fluconazole and miconazole. Their main disadvantages are narrow antibacterial spectrum, unsatisfactory pharmacokinetic curves, obvious drug resistance and toxic side effects, which limit their clinical application.
[0003] Classical CYP51 inhibitors can be divided into three parts: (1) the azole ring part, which is the most important structural fragment for exerting activity. The azole part is perpendicular to the porphyrin plane and coordinates with Fe2+ through the N-3 or N-4 atom of the azole ring, preventing CYP51 from binding to the substrate molecule and exerting inhibitory activity; (2) the aromatic ring; (3) the large non-polar part of the molecule, which extends into a narrow protein cavity (substrate entrance channel). Therefore, the hydrophobic fragment is structurally modified to fully occupy the protein cavity, in order to obtain a CYP51 inhibitor with high efficiency, broad spectrum, anti-resistance and low toxicity for the treatment of invasive fungal infections.

[0090] Pharmacological studies of the present invention
[0091] The in vitro antifungal activities of compounds C01-C18 were determined by the two-fold concentration dilution method.
[0092] The experiment was conducted according to the 2003 edition of the spore-forming filamentous fungi susceptibility test protocol published by the National Committee for Clinical Laboratory Standards (NCCLS) of the United States.
[0093] Positive control drugs: Fluconazole and Miconazole.
[0094] Test strains: Seven test fungi were obtained through public channels and then preserved by the Microbiology Teaching and Research Department of Shenyang Pharmaceutical University, namely Candida albicans (CPCC400616 and ATCCSC5314), Cryptococcus neoformans (CGMCC2.3161), Candida zeylanoides CGMCC2.3739, Candida krusei (AS 2.1045), Candida glabrata (ATCC 22019) and Candida glabrata.
[0095] Preparation of target compound and control drug stock solutions: Weigh 4 mg of target compound and positive control drug respectively, dissolve in 5 mL of DMSO, add 5 mL of Tween 80 and 4.0 mL of distilled water to prepare stock solutions, and store at 4°C for future use.
[0096] Determination of in vitro minimum inhibitory concentration: Add RPM1640 culture medium to the 96-well plate, add 180 μL to the first well, add 100 μL to the growth control well and the experimental well, and add 200 μL to the blank control well. Then add 20 μL of the drug sample stock solution to the first well, mix well, and then aspirate 100 μL, and transfer it to the second well. After mixing well in the second well, aspirate 100 μL again, transfer it to the third well, and so on to all the experimental wells. No drug sample stock solution is added to the growth control well and the blank control well. Then add 100 μL of the prepared and diluted to 1×10 3 ~10 3 cuf / mL bacterial suspension. The 96-well plate was cultured in a 35°C incubator. The MIC values of Candida albicans, Candida tropicalis, Candida krusei, Candida glabrata and Candida glabrata were read after 24 hours of culture, and the MIC values of Cryptococcus neoformans were read after 72 hours of culture. All experiments were performed at least three times independently, and the experimental error did not exceed 10%.
[0097]
[0098] Note: MIC: minimum inhibitory concentration, Fluconazole: fluconazole, Miconazole: miconazole, C.alb: Candida albicans, C.alb(5314): Candida albicans SC5314, C.par: Candida glabrata, C.gla: Candida glabrata, C.kru: Candida krusei, C.tro: Candida tropicalis, C.neo: Cryptococcus neoformans.
[0099] It can be seen from the above that C01-C18 of the present invention has better in vitro antifungal activity, and the antifungal activity of some compounds is much better than that of positive drugs, and the antibacterial spectrum is also wider. The acrylamide compounds containing azole structures designed and synthesized by the present invention have strong antifungal activity and significantly improve their antibacterial effect compared with positive drugs.
