FK506-binding protein 35, FKBP35, has been implicated as an essential malarial enzyme. Rapamycin and FK506 exhibit antiplasmodium activity in cultured parasites. However, due to the highly conserved nature of the binding pockets of FKBPs and the immunosuppressive properties of these drugs, there is a need for compounds that selectively inhibit FKBP35 and lack the undesired side effects. In contrast to human FKBPs, FKBP35 contains a cysteine, C106, adjacent to the rapamycin binding pocket, providing an opportunity to develop targeted covalent inhibitors of Plasmodium FKBP35. Here, we synthesize inhibitors of FKBP35, show that they directly bind FKBP35 in a model cellular setting, selectively covalently modify C106, and exhibit antiplasmodium activity in blood-stage cultured parasites.
On the role of synthesized hydroxylated chalcones as dual functional amyloid-β aggregation and ferroptosis inhibitors for potential treatment of Alzheimer's disease

In addition to amyloid cascade hypothesis, ferroptosis – a recently identified cell death pathway associated with the accumulation of lipid hydroperoxides – was hypothesized as one of the main forms of cell death in Alzheimer's disease. Herein, a series o

An Inexpensive and Scalable Synthesis of Shld
J?rgensen, Frederik Pr?stholm,Bols, Mikael
, p. 6050 - 6055 (2018/05/24)
A synthesis of the important FKBP ligand Shld is reported. The synthesis avoids stoichiometric use of expensive and chiral reagents, maintains enantioselectivity and provides a high overall yield (39%). The main features in the method are enantioselective alkylation for preparation of the phenyl acetic acid moiety (building block A), catalytic enantioselective reduction for obtaining the chiral diaryl-1-propanol (building block C), and direct acylation of S-pipecolic tartrate rather than use of expensive Fmoc-pipecolic acid. The assembly of the building blocks A-C is reversed in comparison to previous synthesis, which also eliminates the need for protective groups.
Discovery of novel human inosine 5′-monophosphate dehydrogenase 2 (hIMPDH2) inhibitors as potential anticancer agents

The enzyme inosine 5′-monophosphate dehydrogenase (IMPDH) catalyzes an essential step in the de novo biosynthesis of guanine nucleotides, and thus regulates the guanine nucleotide pool required for cell proliferation. Of the two isoforms, human IMPDH type 2 (hIMPDH2) is a validated molecular target for potential immunosuppressive, antiviral and anticancer chemotherapy. In search of newer hIMPDH2 inhibitors as potential anticancer agents, three novel series (A: 5-aminoisobenzofuran-1(3H)-one, B: 3,4-dimethoxyaniline and C: benzo[d]-[1,3]dioxol-5-ylmethanamine) were synthesized and evaluated for in vitro and cell-based activities. A total of 37 molecules (29–65) were screened for their in vitro hIMPDH2 inhibition, with particular emphasis on establishing their structure–activity relationship (SAR) trends. Eight compounds (hits, 30, 31, 33–35, 37, 41 and 43) demonstrated significant enzyme inhibition (>70% @ 10 μM); especially the A series molecules were more potent than B series (50 values for the hits ranged from 0.36 to 7.38 μM. The hits displaying >80% hIMPDH2 inhibition (30, 33, 35, 41 and 43) were further assessed for their cytotoxic activity against cancer cell lines such as MDA-MB-231 (breast adenocarcinoma), DU145 (prostate carcinoma), U87 MG (glioblastoma astrocytoma) and a normal cell line, NIH-3T3 (mouse embryonic fibroblast) using MTT assay. Most of the compounds exhibited higher cellular potency against cancer cell lines and notably lower toxicity towards NIH-3T3 cells compared to mycophenolic acid (MPA), a prototypical hIMPDH2 inhibitor. Two of the series A hits (30 and 35) were evaluated in human peripheral blood mononuclear cells (hPBMC) assay and found to be better tolerated than MPA. The calculated/predicted molecular and physicochemical properties were satisfactory with reference to drug-likeness. The molecular docking studies clearly demonstrated crucial interactions of the hits with the cofactor-binding site of hIMPDH2, further providing critical information for refining the design strategy. The present study reports the design and discovery of structurally novel hIMPDH2 inhibitors as potential anticancer agents and provides a guide for further research on the development of safe and effective anticancer agents, especially against glioblastoma.
