Linagliptin or Tradjenta is a medication used to treat diabetes mellitus type 2. 3d illustration
Rendered remdesivir molecule in 3D, an experimental drug from Gilead, used to cure the first case of COVID-19 (or 2019-nCoV) in the United States (for a patient at Seattle, Washington). The model showed accurate atom connection and stereochemistry, based on the chemical structure available in public space from U.S. National Library of Medicine, which was professionally checked. Color symbols - green white =carbon, orange=oxygen, blue=nitrogen, white=hydrogen, red=phosphorus
The coronavirus 3CL hydrolase enzyme is essential for the maturation of the virus. It can be a promising target for drugs that would inhibit cleavage of the viral polyprotein and prevent spread of the infection. Source: PDB entry 6LU7
A ball and stick + ribbons model of human Interleukin 2 or IL-2. Interleukin is a hormone which acts as a signalling molecule for the immune system.
3D cartoon and Gaussian surface models, chain id color scheme, PDB 2v0z, white background
