Mt KARI-IN-4 (compound 5c) is a highly effective inhibitor of Mycobacterium tuberculosis ketol-acid reductoisomerase (Mtb KARI), demonstrating a Ki value of 5.48 μM. Additionally, Mt KARI-IN-4 displays inhibitory properties against Mtb H37Rv, with a minimum inhibitory concentration (MIC) of 0.78 μM. Importantly, this compound exhibits low levels of cytotoxicity, as evident from its half-maximal inhibitory concentration (IC 50 ) value of over 72 μg/mL against human embryonic kidney cells (HEK) [1].
GSK3368715 is an orally active, reversible, and S-adenosyl-L-methionine (SAM) uncompetitive type I protein arginine methyltransferases (PRMTs) inhibitor (IC50s: 3.1 nM (PRMT1), 48 nM (PRMT3), 1148 nM (PRMT4), 5.7 nM (PRMT6), 1.7 nM (PRMT8)). It has strong anti-cancer activity.
4'-Ethynyl-2'-deoxyadenosine (4'-E-dA) is a nucleoside reverse transcriptase (RT) inhibitor. It is potent against drug-resistant HIV variants (EC50: 98 nM in MT-4 cells for anti-HIV-1 activity).
Mavorixafor trihydrochloride is a selective and orally available CXCR4 antagonist (IC50: 13 nM against CXCR4 125I-SDF binding) and also inhibits the replication of T-tropic HIV-1 (NL4.3 strain) in MT-4 cells and PBMCs (IC50s: 1 and 9 nM).
AMD 3465 also potently inhibits the replication of X4 HIV strains (IC50: 1-10 nM). However, it has no effect on CCR5-using (R5) viruses. AMD 3465 (GENZ-644494) is a potent antagonist of CXCR4, inhibits binding of 12G5 mAb and CXCL12AF647 to CXCR4, with IC
Furamidine is also a selective and cell-permeable protein arginine methyltransferase 1 (PRMT1) inhibitor with an IC50 of 9.4 μM. Furamidine is selective for PRMT1 over PRMT5, PRMT6, and PRMT4 (CARM1) (IC50s of 166 μM, 283 μM, and >400 μM, respectively). Furamidine (DB75) is abisbenzamidine derivative and an antiparasite agent. Furamidine is a potent, reversible and competitive tyrosyl-DNA phosphodiesterase 1 (TDP-1) inhibitor. Inhibition of TDP-1 by Furamidine is effective both with single- and double-stranded DNA substrates but is slightly stronger with the duplex DNA.
GSK3368715, a potent inhibitor of type I protein arginine methyltransferases (PRMT), could inhibit PRMT1, 3, 4, 6 and 8 with Kiapp vaules ranging from 1.5 to 81 nM.
