Abstract:
The incidence of type 2 diabetes mellitus (T2DM) has been on the increase in recent times. Although several oral treatments for T2DM are available, some of them have been found to elicit undesirable side effects. This therefore underscores the need for new treatment options with lesser side effects than the existing ones for people with T2DM. Free fatty acid receptor 1 (FFAR1), also known as GPR40, belongs to a class of G-protein coupled receptors that are encoded by FFAR1 genes in humans. It is expressed in the pancreatic β-cells and it is activated by medium- and long-chain saturated and unsaturated fatty acids. Thus it responds to endogenous medium and long chain unsaturated fatty acids, resulting in enhancement of insulin secretion during increased glucose levels. The glucose dependency of insulin secretion has made this receptor a very good target for developing therapies that could be efficacious with fewer side effects than the existing therapies for the treatment of T2DM. Given that tremendous efforts have been made in recent times in developing novel FFAR1 agonists with antidiabetic potentials, this article provides a current status of knowledge on the efforts made so far in developing novel FFAR1 agonists that would be of relevance in the management of T2DM.
Insights
The rising incidence of type 2 diabetes mellitus (T2DM) necessitates novel treatments. Research focuses on Free Fatty Acid Receptor 1 (FFAR1) agonists for safer, glucose-dependent insulin secretion enhancement.
Area of Science:
- Endocrinology and Pharmacology
- Molecular and Cellular Biology
Background:
- Type 2 Diabetes Mellitus (T2DM) incidence is increasing globally.
- Existing oral T2DM treatments can cause adverse side effects.
- There is a critical need for novel therapeutic strategies with improved safety profiles.
Purpose of the Study:
- To review the current status of novel Free Fatty Acid Receptor 1 (FFAR1) agonists development.
- To highlight FFAR1 as a promising therapeutic target for T2DM management.
- To discuss the potential of FFAR1 agonists in improving T2DM treatment efficacy and safety.
Main Methods:
- Literature review of recent research on FFAR1 agonists.
- Analysis of FFAR1's role in glucose-dependent insulin secretion.
- Evaluation of the antidiabetic potential and side effect profiles of FFAR1 agonists.
Main Results:
- FFAR1 (GPR40) is a G-protein coupled receptor expressed in pancreatic β-cells.
- FFAR1 activation by fatty acids enhances glucose-dependent insulin secretion.
- Numerous FFAR1 agonists are under investigation for T2DM treatment.
Conclusions:
- FFAR1 agonists represent a promising therapeutic avenue for T2DM.
- The glucose-dependent mechanism of FFAR1 offers potential for reduced hypoglycemia risk.
- Continued development of FFAR1 agonists may lead to safer and more effective T2DM therapies.

Acidity of 1-Alkynes
The acidic strength of hydrocarbons follows the order: Alkynes > Alkenes > Alkanes. The strength of an acid is commonly expressed in units of pKa — the lower the pKa, the stronger the acid. Among the hydrocarbons, terminal alkynes have lower pKa values and are, therefore, more acidic. For example, the pKa values for ethane, ethene, and acetylene are 51, 44, and 25, respectively, as shown here.
