Dhfr Inhibitors

Background: Dihydrofolate reductase (DHFR) has been known for decades as a molecular target for antibacterial, antifungal and anti-malarial treatments. This enzyme is becoming increasingly important in the design of new anticancer drugs, which is confirmed by numerous studies including modelling, synthesis and in vitro biological research. This review aims to present and discuss some remarkable recent advances on the research of new DHFR inhibitors with potential anticancer activity. Methods: The scientific literature of the last decade on the different types of DHFR inhibitors has been searched. The studies on design, synthesis and investigation structure-activity relationship were summarized and divided into several subsections depending on the leading molecule and its structural modification. Various methods of synthesis, potential anticancer activity and possible practical applications as DHFR inhibitors of new chemical compounds were described and discussed. <p> Results: This review presents the current state of knowledge on the modification of known DHFR inhibitors and the structures and searching for over eighty new molecules, designed as potential anticancer drugs. In addition, DHFR inhibitors acting on thymidylate synthase (TS), carbon anhydrase (CA) and even DNA-binding are presented in this paper. <p> Conclusion: Thorough physicochemical characterization and biological investigations it is possible to understand structure-activity relationship of DHFR inhibitors. This will enable even better design and synthesis of active compounds, which would have the expected mechanism of action and the desired activity.

Current traditional drugs such as enzyme inhibitors and receptor agonists/antagonists present inherent limitations due to occupancy-driven pharmacology as the mode of action. Proteolysis targeting chimeras (PROTACs) are composed of an E3 ligand, a connecting linker and a target protein ligand, and are an attractive approach to specifically knockdown-targeted proteins utilizing an event-driven mode of action. The length, hydrophilicity and rigidity of connecting linkers play important role in creating a successful PROTAC. Some PROTACs with a triazole linker have displayed promising anticancer activity. This review provides an overview of PROTACs with a triazole scaffold and discusses its structure–activity relationship. Important milestones in the development of PROTACs are addressed and a critical analysis of this drug discovery strategy is also presented.

Prevalent Disease

: Cancer is a heterogeneous disease characterized by an abnormal and uncontrolled division of the cells leading to tumors that invade the adjacent normal tissues. After cardiovascular diseases, it is the second most prevalent disease accounting for one in every six deaths worldwide. This alarming rate thus, demands an urgent need to investigate more effective drugs to combat the said disease. Oxygen and nitrogen-based heterocyclic compounds have shown remarkable therapeutic activity towards several diseases, including cancer. In this review, we have attempted to summarize the work done in the last decade (2009-2019), highlighting the anticancer activity of pyrido fused five-membered heterocyclic ring derivatives. Additionally, we have focused on seven heterocyclic pyridine fused rings: Imidazopyridine, Triazolopyridine, Pyrrolopyridine, Pyrazolopyridines, Thienopyridine, and Isoxazolopyridine. A total of forty-nine compounds have been studied based on their in-vitro cytotoxic activity and their structure-activity relationship, underlining the anticancer activity of their various pharmacophores and substituents. This review, therefore, aims to draw the attention of the researchers worldwide towards the enormous scope of development of heterocyclic drug compounds, focussing mainly on pyrido fused five-membered heterocyclic rings as anticancer drugs.

Pharmacokinetic Evaluation

Compound 1 is a curcumin di-O-2,2-bis(hydroxymethyl)propionate that shows significant in vitro and in vivo inhibitory activity against MDA-MB-231 cells with eight to ten-fold higher potency than curcumin. Here, we modified the α-position (C-4 position) of the central 1,3-diketone moiety of 1 with polar or nonpolar functional groups to afford a series of 4,4-disubstituted curcuminoid 2,2-bis(hydroxymethyl)propionate derivatives and evaluated their anticancer activities. A clear structure–activity relationship of compound 1 derivatives focusing on the functional groups at the C-4 position was established based on their anti-proliferative effects against the MDA-MB-231 and HCT-116 cell lines. Compounds 2–6 are 4,4-dimethylated, 4,4-diethylated, 4,4-dibenzylated, 4,4-dipropargylated and 4,4-diallylated compound 1, respectively. Compounds 2m–6m, the ester hydrolysis products of compounds 2–6, respectively, were synthesized and assessed for anticancer activity. Among all compound 1 derivatives, compound 2 emerged as a potential chemotherapeutic agent for colon cancer due to the promising in vivo anti-proliferative activities of 2 (IC50 = 3.10 ± 0.29 μM) and its ester hydrolysis product 2m (IC50 = 2.17 ± 0.16 μM) against HCT-116. The preliminary pharmacokinetic evaluation of 2 implied that 2 and 2m are main contributors to the in vivo efficacy. Compound 2 was further evaluated in an animal study using HCT-116 colon tumor xenograft bearing nude mice. The results revealed a dose-dependent efficacy that led to tumor volume reductions of 27%, 45%, and 60% at 50, 100, and 150 mg/kg doses, respectively. The established structure–activity relationship and pharmacokinetic outcomes of 2 is the guidance for future development of 4,4-disubstituted curcuminoid 2,2-bis(hydroxymethyl)- propionate derivatives as anticancer drug candidates.
