Usibye kuba okiside cyangwa kugabanuka kugeza kuri 2,5-dimethoxybenzoic aside, benzonitrile cyangwa inzoga ya benzyl, 2,5-dimethoxybenzaldehyde ubwayo nayo ifite agaciro kihariye ko kuyikoresha. Mugukora ibintu hamwe nubwoko butandukanye bwamatsinda akora, molekile zibiyobyabwenge zifite imiterere ningaruka zitandukanye zirashobora kuboneka. Indwara ya Parkinson (PD) ni indwara ikunze kwibasira neurodegenerative, kandi ibimenyetso byayo nyamukuru by’amavuriro birimo guhinda umushyitsi, gukomera, ingorane zo kugenda, guhagarara k'umubiri no guhungabana kwimiterere. Iterambere rindi rizaganisha no kumenyekana, imyumvire, guhungabana kwibuka no guta umutwe bigaragara. Kugeza ubu, kuvura PD bikubiyemo ahanini kuvura ibiyobyabwenge, kubaga no kuvura gene. Mu kuvura ibiyobyabwenge, wasangaga phenamidine igira ingaruka nziza kuri PD, ifite uburozi buke n’umutekano mwiza, kandi synthesis ya phenamidine isaba gukoresha 2,5-dimethoxybenzaldehyde nkibikoresho byo gutangira.
Ukurikije uburyo bwa synthesis bwatanzwe mubitabo, 2,5-dimethoxybenzaldehyde iboneka cyane cyane mugukora 1,4-dimethoxybenzene hamwe na agent formylation. Ibikoresho byo gukora birimo (1) imvange ya 1,1-dichloromethyl ether na titanium tetrachloride; (2) imvange ya N, N-dimethylformamide na fosifore oxychloride, imvange ya N, N-dimethylformamide na chloride ya oxalyl; (3) imvange ya N, N-dimethylformamide na thionyl chloride cyangwa uruvange rwa urotropine na chloride ya magnesium. Nyamara, ubu buryo busaba gukoresha umubare munini wa titanium tetrachloride, fosifore oxychloride cyangwa thionyl chloride. Izi reagent ntizihindagurika kandi zirashobora kubora byoroshye, kandi gaze ya gaze ya hydrochloric aside irekurwa mugihe cyo kubyitwaramo, bitangiza ibidukikije kandi bifite ibisabwa byinshi mubikorwa.
Uburyo bushya bwo guhuza ibitekerezo bwatanzwe. Ubu buryo bukoresha 1,4-dimethoxybenzene na formaldehyde nkibikoresho fatizo, kandi bigakora reaction ya fotooxidative ihuza imbere ya ogisijeni na catalizator munsi yumucyo wubururu kugirango uhuze neza 2,5-dimethoxybenzaldehyde. Ubu buryo bukoresha ogisijeni cyangwa umwuka nka okiside, ntabwo bitanga gaze ya aside, kandi byangiza ibidukikije. Mubyongeyeho, ubu buryo bukoresha cobalt ihendutse nka catalizator, iri hasi kubiciro kandi ikwiranye ninganda zikoreshwa.
