Spacered With Tetrazole Oleanolic and Ursolic Indolo-Acids Are Strong Inhibitors of α-Glucosidase.

A series of oleanane and ursane-type derivatives conjugated with a tetrazole cycle were obtained by 2 + 3 cycloaddition of C28-cyanoalkyl esters with sodium azide in the presence of NHCl. It was shown that 2,3-indolo-oleanolic and ursolic acids with a tetrazole moiety exhibited strong inhibitory activity against α-glucosidase with IC values of 1.15 and 1.

Multi-Year Multi-Indication Agreements for Supporting Patient Access to Oncology Medicines with Multiple Indications: An Experimental Approach or Here to Stay?

Over the past decade, an increasing number of oncology medicines with indications for multiple cancer types have been delivering benefits to patients. To ensure these products reach patients, pricing and reimbursement systems have had to adapt to address the value assessment, time-to-access, affordability, and budget uncertainty challenges this creates. Multi-year multi-indication (MYMI) agreements are made between payers and manufacturers and aim to ensure that patients have access to effective treatments for multiple conditions over time; this includes future indications of the treatment.

What Kills Mature Street and Park Trees in Cities? Systematic Quantitative Review of Published Case Studies.

Street and park trees often endure harsher conditions, including increased temperatures and drier soil and air, than those found in urban or natural forests. These conditions can lead to shorter lifespans and a greater vulnerability to dieback. This literature review aimed to identify confirmed causes of street and park tree dieback in urban areas from around the world.

Conjugation of Triterpenic Acids with 3-Aminoquinuclidine Moiety: An Approach to Acetylcholinesterase Mixed or Uncompetitive Type Inhibitors.

Alzheimer's disease (AD) poses a significant public health issue. Despite the fact that today there are several methods of maintenance therapy, one of the most widely used methods is designed to correct the deficiency of acetylcholine. In the search for new potential inhibitors of cholinesterase enzymes, eight new derivatives of 3-oxo- or 2,3-indolo-triterpenic acid conjugated with amino-quinuclidine bicyclic cores were designed and synthesized.
