Cover illustration: Eugenol is a natural mol­ecule that exhibits versatile properties useful in various domains. There is increasing inter­est from the scientific and industrial community in eugenol-based polymers and this bioactive compound has high potential as a therapeutic agent since it has anti­parasitic, anti­viral, anti­bacterial, anti­fungal, anti­cancer, anti­oxidant and anti-inflammatory activities. Vanillylformamide [systematic name: N-(4-hy­droxy-3-meth­oxy­benz­yl)form­amide] and eugenol can be considered to be `isosteres' of each other, since they share comparable mol­ecular shape and volume.
