SAR revealed tolerance for 4-Cl isosteres with 4-F (8), 3-F (9), 3-CH₃ (22), and 4-C(CH₃)₃ (27) (23.7–71 μM) and with 3-Cl (3), 4-CH₃ (21), and 4-CH(CH₃)₂ (26) (8.1–13.0 μM). Imine carbon alkylation identified a methyl/ethyl binding pocket that also accommodated a CH₂OH moiety (75; 2,2′-bis[1-(4-chlorophenyl)-2-hydroxyethylidene]carbonimidic dihydrazide). Analogues 1, 27 (2,2′-bis{[4-(1,1-dimethylethyl)phenyl]methylene}carbonimidic dihydrazide), and 69 (2,2′-bis[1-(4-chlorophenyl)ethylidene]carbonimidic dihydrazide hydrochloride) were active against 24 clinical MRSA and MSSA isolates. No dose-limiting cytotoxicity at ≥2× MIC or hemolysis at ≥8× MIC was observed. Polymyxin B addition engendered Escherichia coli and Pseudomonas aeruginosa Gram-negative activity MIC’s of 4.2–21.6 μM. 1 and 75 displayed excellent microsomal stability, intrinsic clearance, and hepatic extraction ratios with T1/2 > 247 min, CLint < 7 μL/min/mg protein, and EH < 0.22 in both human and mouse liposomes for 1 and in human liposomes for 75.]]> Wed 02 Mar 2022 14:27:39 AEDT ]]> Inhibition of dynamin mediated endocytosis by the dynoles-synthesis and functional activity of a family of indoles https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:8338 Sat 24 Mar 2018 08:37:03 AEDT ]]> Iminochromene inhibitors of Dynamins I and II GTPase activity and Endocytosis https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:11334 Sat 24 Mar 2018 08:13:29 AEDT ]]> The Pthaladyns: GTP competitive inhibitors of Dynamin I and II GTPase derived from virtual screening https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:10254 Sat 24 Mar 2018 08:13:07 AEDT ]]> Development of 1,8-naphthalimides as clathrin inhibitors https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21428 50 ≈ 18 μM). A second library targeting the 4-aminobenzyl moiety was developed, and four analogues displayed comparable activity (26, 27, 28, 34 with IC50 values of 22, 16, 15, and 15 μM respectively) with a further four (24, 25, 32, 33) more active than 18 with IC50 values of 10, 6.9, 12, and 10 μM, respectively. Docking studies rationalized the structure–activity relationship (SAR) with the biological data. 3-Sulfo-N-benzyl-1,8-naphthalimide, potassium salt (25) with an IC50 ≈ 6.9 μM, is the most potent clathrin terminal domain–amphiphysin inhibitor reported to date.]]> Sat 24 Mar 2018 08:05:47 AEDT ]]> Development of second-generation indole-based dynamin GTPase inhibitors https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20159 Sat 24 Mar 2018 07:51:36 AEDT ]]> Serine-threonine protein phosphatase inhibitors: development of potential therapeutic strategies https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3185 Sat 24 Mar 2018 07:18:09 AEDT ]]> Identification and optimization of mechanism-based fluoroallylamine inhibitors of lysyl oxidase-like 2/3 https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41886 PXS-5120A (12k), a potent, irreversible inhibitor that is >300-fold selective for LOXL2 over LOX. PXS-5120A also shows potent inhibition of LOXL3, an emerging therapeutic target for lung fibrosis. Key to the development of this compound was the utilization of a compound oxidation assay. PXS-5120A was optimized to show negligible substrate activity in vitro for related amine oxidase family members, leading to metabolic stability. PXS-5120A, in a pro-drug form (PXS-5129A, 12o), displayed anti-fibrotic activity in models of liver and lung fibrosis, thus confirming LOXL2 as an important target in diseases where collagen cross-linking is implicated.]]> Mon 15 Aug 2022 15:37:55 AEST ]]> Structure-Activity Relationships of Daptomycin Lipopeptides https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40845 Mon 08 Aug 2022 15:39:55 AEST ]]>
