RESUMO
Chemical investigation of the lichen Dirinaria applanata led to isolate nine compounds including a new hopane derivative, 1ß-acetoxy-21α-hopane-3ß,22-diol (1) together with six phenolic compounds naming divaricatinic acid (2), methyl divaricatinate (3), methyl-ß-orcinolcarboxylate (4), methyl haematommate (5), divarinol (6), ramalinic acid A (7), and two xanthones namely lichenxanthone (8), 4,5-dichlorolichenxanthone (9). Their structures were elucidated by spectroscopic data in combination with published literature. Except compound 2, all compounds were isolated from this species for the first time.

Developmental processes are cascades of biological changes linked with information transfer, growth, and differentiation during the life cycle of an organism. Lipid metabolism plays a vital role in the life cycle of organisms. Drosophila models grant numerous advantages in investigating the underlying mechanisms of each process as well as their connections. In each section of this review, we will discuss multiple studies revealing the function of lipid-related genes in different stages of early development: spermatogenesis, oogenesis, embryogenesis along with late development in life cycle of Drosophila.
