The study is the first step towards a safe bioeconomy from an eco-toxicological stance, and which uses sustainable resources and processes to reduce environmental burdens significantly. |
| Scientists develop new method for creating promising new sulphur-based medicines Posted: 14 Feb 2022 09:12 AM PST A key technical challenge in creating new sulphur-based medicines has been overcome, leading to the prospect of many new therapeutic 'weapons' in the fight against disease and illness. Every successful drug has a part of it that physically fits into the exact biochemical pathway it is trying to disrupt. This part of the drug is known as a 'pharmacophore' and generating new ones is a key goal in drug discovery. Sulphur-based pharmacophores are highly versatile and seen as very promising to drug developers but are rare due to the challenges of synthesising them. Now, scientists have designed a method to generate sulphur pharmacophores using a catalyst specially developed by the scientists themselves, known as pentanidium. Their method could be used to synthesise a broad range of new pharmacophores that could be paired with different types of molecules to form new drugs. |
| A new microscope allows for high-throughput 3D adaptive optical imaging Posted: 14 Feb 2022 08:18 AM PST Microscopes are an important tool in biomedical research as it allows for detailed observation and imaging of tissues. Since biological materials are opaque by their nature, severe light scattering occurs as light travels through tissues, which induces a high level of background noise and complex optical aberration. Therefore, typical light microscopes mostly allow us to see the surface of the tissues, and details that are multiple cell layers deep are out of reach for many microscopes. This makes taking high-resolution optical images of microstructures deep inside tissues highly challenging. |
