3d structure of Gedatolisib, an agent targeting the phosphatidylinositol 3 kinase (PI3K) and mammalian target of rapamycin (mTOR) in the PI3K/mTOR pathway, with potential antineoplastic activity.
Structural model of Benzene molecule
Proliferating cell nuclear antigen (PCNA) is a DNA clamp that acts as a processivity factor for DNA polymerase δ in eukaryotic cells and is essential for replication. PCNA is a homotrimer and achieves its processivity by encircling the DNA, where it acts as a scaffold to recruit proteins involved in DNA replication, DNA repair, chromatin remodeling and epigenetics. 3D cartoon and Gaussian surface models, chain instance color scheme, based on PDB 3wgw, white background.

Methanol, also known as methyl alcohol among others, is a chemical with the formula CH3OH (often abbreviated MeOH).
Inside protein molecule
Potassium permanganate (KMnO4) with chemical structure , a common chemical compound that combines manganese oxide ore with potassium hydroxide.
A model of a molecule of arginine, an amino acid. Amino acids are the building blocks of proteins and have many functions in metabolism. In particular, Arginine has an important function in the immune system, wound healing and cell division.
Prednisone is a glucocorticoid medication mostly used to suppress the immune system and decrease inflammation in conditions such as asthma, COPD, and rheumatologic diseases.
Chemical formula of Aldosterone
Iobenguane I-131 cancer drug molecule (radiopharmaceutical). 3D rendering. Atoms are represented as spheres with conventional color coding
