Isicelo:

I-4-Amino-3,5-Dichloropyridine (i-CAS: 22889-78-7) iphakathi kwe-Roflumilast (i-CAS: 162401-32-3).I-Roflumilast iyi-elective oral phosphodiesterase-4 (PDE-4) inhibitor kanye ne-benzamide compound.Yasungulwa yinkampani yaseJalimane i-Altana ngo-1993 futhi iyona kuphela inhibitor yomlomo ye-PDE-4 esetshenziselwa ukwelapha izifo zemigudu yokuphefumula evunyelwe ukudayiswa.I-Roflumilast umuthi wokuqala wohlobo lwayo ukukhomba isifo esiyingozi esingalapheki esivimbela amaphaphu (COPD), futhi iphinde ibe umuthi wokuqala womlomo wokulwa nokuvuvukala owenzelwe iziguli ezine-COPD.
