Dipeptidyl peptidase IV and its inhibitors: therapeutics for type 2 diabetes and what else?
    Journal of medicinal chemistry, 2014, Mar-27, Volume: 57, Issue:6

    The proline-specific dipeptidyl aminopeptidase IV (DPP IV, DPP-4, CD26), widely expressed in mammalians, releases X-Pro/Ala dipeptides from the N-terminus of peptides. DPP IV is responsible of the degradation of the incretin peptide hormones regulating blood glucose levels. Several families of DPP IV inhibitors have been synthesized and evaluated. Their positive effects on the degradation of the incretins and the control of blood glucose levels have been demonstrated in biological models and in clinical trials. Presently, several DPP IV inhibitors, the "gliptins", are approved for type 2 diabetes or are under clinical evaluation. However, the gliptins may also be of therapeutic interest for other diseases beyond the inhibition of incretin degradation. In this Perspective, the biological functions and potential substrates of DPP IV enzymes are reviewed and the characteristics of the DPP IV inhibitors are discussed in view of type 2 diabetes and further therapeutic interest.

The many faces of the adamantyl group in drug design.
    European journal of medicinal chemistry, 2011, Volume: 46, Issue:6

    Adamantyl-based compounds are used clinically for the treatment of neurological conditions, as anti-viral agents and as agents against type 2 diabetes. The value of the adamantyl group in drug design is multidimensional. The hydrophobic substituent constant for the adamantyl group has been estimated from the calculated partition coefficients (clogP values) of 31 adamantyl-bearing compounds in the clinic or in development as πadamantyl=3.1, which indicates that the logP value of a compound with high water solubility (logP<<0) could be moved with an adamantyl-based modification to a region that is more clinically useful. The steric bulk of the adamantyl group can: (i) restrict or modulate intramolecular reactivity; and (ii) impede the access of hydrolytic enzymes, thereby increasing drug stability and plasma half life. The value of the adamantyl group in drug design has been recognized most recently in the design of agents to treat iron overload disease (in development), malaria (in clinical trials) and type 2 diabetes (in the clinic).

Medicinal chemistry approaches to the inhibition of dipeptidyl peptidase-4 for the treatment of type 2 diabetes.
    Bioorganic & medicinal chemistry, 2009, Mar-01, Volume: 17, Issue:5

    Emerging as an epidemic of the 21st century type 2 diabetes has become a major health problem throughout the globe. The number of deaths attributable to diabetes reflects the insufficient glycemic control achieved with the treatments used in recent past. DPP-4 inhibitors have been investigated as a new therapy with novel mechanisms of action and improved tolerability. DPP-4, a protease that specifically cleaves dipeptides from proteins and oligopeptides after a penultimate N-terminal proline or alanine, is involved in the degradation of a number of neuropeptides, peptide hormones and cytokines, including the incretins GLP-1 and GIP. As soon as released from the gut in response to food intake, GLP-1 and GIP exert a potent glucose-dependent insulinotropic action, thereby playing a key role in the maintenance of post-meal glycemic control. Consequently, inhibiting DPP-4 prolongs the action of GLP-1 and GIP, which in turn improves glucose homeostasis with a low risk of hypoglycemia and potential for disease modification. Indeed, clinical trials involving diabetic patients have shown improved glucose control by administering DPP-4 inhibitors, thus demonstrating the benefit of this promising new class of antidiabetics. Intense research activities in this area have resulted in the launch of sitagliptin and vildagliptin (in Europe only) and the advancement of a few others into preregistration/phase 3, for example, saxagliptin, alogliptin and ABT-279. Achieving desired selectivity for DPP-4 over other related peptidases such as DPP-8 and DPP-9 (inhibition of which was linked to toxicity in animal studies) and long-acting potential for maximal efficacy (particularly in more severe diabetic patients) were the major challenges. Whether these goals are achieved with the present series of inhibitors in the advanced stages of clinical development is yet to be confirmed. Nevertheless, treatment of this metabolic disorder especially in the early stages of the disease via DPP-4 inhibition has been recognized as a validated principle and a large number of inhibitors are presently in various stage of pre-clinical/clinical development. Sitagliptin is a new weapon in the arsenal of oral antihyperglycemic agents. This review will focus on the journey of drug discovery of DPP-4 inhibitors for oral delivery covering a brief scientific background and medicinal chemistry approaches along with the status of advanced clinical candidates.

Discovery of 3H-imidazo[4,5-c]quinolin-4(5H)-ones as potent and selective dipeptidyl peptidase IV (DPP-4) inhibitors.
    Bioorganic & medicinal chemistry, 2012, Oct-01, Volume: 20, Issue:19

    In recent years, dipeptidyl peptidase IV inhibitors have been noted as valuable agents for treatment of type 2 diabetes. Herein, we report the discovery of a novel potent DPP-4 inhibitor with 3H-imidazo[4,5-c]quinolin-4(5H)-one as skeleton. After efficient optimization of the lead compound 2a at the 7- and 8-positions using a docking study, we found 28 as a novel DPP-4 inhibitor with excellent selectivity against various DPP-4 homologues. Compound 28 showed strong DPP-4 inhibitory activity compared to marketed DPP-4 inhibitors. We also found that a carboxyl group at the 7-position could interact with the residue of Lys554 to form a salt bridge. Additionally, introduction of a carboxyl group to 7-position led to both activity enhancement and reduced risk for hERG channel inhibition and induced phospholipidosis. In our synthesis of compounds with 7-carboxyl group, we achieved efficient regioselective synthesis using bulky ester in the intramolecular palladium coupling reaction.

Emerging drug candidates of dipeptidyl peptidase IV (DPP IV) inhibitor class for the treatment of Type 2 Diabetes.
    Current drug targets, 2009, Volume: 10, Issue:1

    Dipeptidyl peptidase IV (DPP IV) is a key regulator of insulin-stimulating hormones, glucagon-like peptide (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), thus it is a promising target for the treatment of Type 2 Diabetes mellitus (T2DM). Inhibition of plasma DPP IV enzyme leads to enhanced endogenous GLP-1 and GIP activity, which ultimately results in the potentiation of insulin secretion by pancreatic beta-cells and subsequent lowering of blood glucose levels, HbA[1(c)], glucagon secretion and liver glucose production. Various classes of structurally different DPP IV inhibitors are currently being explored and few of them such as Sitagliptin and Vildagliptin were successfully launched. These drugs have been approved as a once-daily oral monotherapy or as a combination therapy with current anti-diabetic agents like pioglitazone, glibenclamide, metformin etc. for the treatment of T2DM. Several other novel DPP IV inhibitors are in pipeline. The present review summarizes the latest preclinical and clinical trial data of different DPP IV inhibitors with a special emphasis on their DPP8/9 fold selectivity and therapeutic advantages over GLP-1 based approach.

    Journal of medicinal chemistry, 2006, Oct-19, Volume: 49, Issue:21

    Dipeptidyl peptidase-IV (DPP-IV) inhibitors are poised to be the next major drug class for the treatment of type 2 diabetes. Structure-activity studies of substitutions at the C5 position of the 2-cyanopyrrolidide warhead led to the discovery of potent inhibitors of DPP-IV that lack activity against DPP8 and DPP9. Further modification led to an extremely potent (Ki(DPP)(-)(IV) = 1.0 nM) and selective (Ki(DPP8) > 30 microM; Ki(DPP9) > 30 microM) clinical candidate, ABT-279, that is orally available, efficacious, and remarkably safe in preclinical safety studies.

Discovery and preclinical profile of Saxagliptin (BMS-477118): a highly potent, long-acting, orally active dipeptidyl peptidase IV inhibitor for the treatment of type 2 diabetes.
    Journal of medicinal chemistry, 2005, Jul-28, Volume: 48, Issue:15

    Efforts to further elucidate structure-activity relationships (SAR) within our previously disclosed series of beta-quaternary amino acid linked l-cis-4,5-methanoprolinenitrile dipeptidyl peptidase IV (DPP-IV) inhibitors led to the investigation of vinyl substitution at the beta-position of alpha-cycloalkyl-substituted glycines. Despite poor systemic exposure, vinyl-substituted compounds showed extended duration of action in acute rat ex vivo plasma DPP-IV inhibition models. Oxygenated putative metabolites were prepared and were shown to exhibit the potency and extended duration of action of their precursors in efficacy models measuring glucose clearance in Zucker(fa/fa) rats. Extension of this approach to adamantylglycine-derived inhibitors led to the discovery of highly potent inhibitors, including hydroxyadamantyl compound BMS-477118 (saxagliptin), a highly efficacious, stable, and long-acting DPP-IV inhibitor, which is currently undergoing clinical trials for treatment of type 2 diabetes.
