The main focus of this review is to introduce readers to the fascinating class of lipid molecules known as norsteroids, exploring their distribution across various biotopes and their biological activities. The review provides an in-depth analysis of various modified steroids, including A, B, C, and D-norsteroids, each characterized by distinct structural alterations. These modifications, which range from the removal of specific methyl groups to changes in the steroid core, result in unique molecular architectures that significantly impact their biological activity and therapeutic potential. The discussion on A, B, C, and D-norsteroids sheds light on their unique configurations and how these structural modifications influence their pharmacological properties. The review also presents examples from natural sources that produce a diverse array of steroids with distinct structures, including the aforementioned A, B, C, and D-nor variants. These compounds are sourced from marine organisms like sponges, soft corals, and starfish, as well as terrestrial entities such as plants, fungi, and bacteria. The exploration of these steroids encompasses their biosynthesis, ecological significance, and potential medical applications, highlighting a crucial area of interest in pharmacology and natural product chemistry. The review emphasizes the importance of researching these steroids for drug development, particularly in addressing diseases where conventional medications are inadequate or for conditions lacking sufficient therapeutic options. Examples of norsteroid synthesis are provided to illustrate the practical applications of this research.

Paraoxonase 1 (PON1) is an antioxidant enzyme that prevents lipid oxidation by hydrolysing lipid peroxides in the oxidised low‐density lipoprotein (LDL) structure, bound to high‐density lipoprotein (HDL) in serum, and exhibits esterase and lactonase activity. In this work, the hPON1 enzyme was purified from human serum using a hydrophobic gel with Sepharose 4B‐L‐tyrosine‐naphthylamine, and the affinity of some steroid derivatives previously isolated from fungal steroid biotransformations was examined on the pure hPON1 enzyme. The results indicate that all these derivaties activate the hPON1 enzyme to a different extent. Additionally, the binding potential of the most active five steroid derivatives to the PON1 enzyme to form a stable complex was explored through molecular docking and molecular dynamics (MD) simulation. The compounds with the highest potency in the enzymatic assay, S‐8 and S‐20, had the highest binding potential to the enzyme. The stability of the complexes formed by the two compounds was assessed and compared to the stability of the unbound enzyme structure. The enzyme‐compound complexes generally had similar stability to the unbound enzyme structure. Together with this, the MD simulation revealed that compound S‐8 would remain inside the enzyme's binding site during the simulation period, unlike compound S‐20. This situation varies according to the respective derivatives’ functional groups and hydrophobic characteristics.
