Design, synthesis, and evaluation of trifluoromethyl ketones as inhibitors of SARS-CoV 3CL protease.

ABSTRACT: A series of trifluoromethyl ketones as SARS-CoV 3CL protease inhibitors was developed. The inhibitors were synthesized in four steps from commercially available compounds. Three different amino acids were explored in the P1-position and in the P2-P4 positions varying amino acids and long alkyl chain were incorporated. All inhibitors were evaluated in an in vitro assay using purified enzyme and fluorogenic substrate peptide. One of the inhibitors showed a time-dependent inhibition, with a K(i) value of 0.3 microM after 4h incubation.

Design, synthesis and biological evaluation of peptidomimetic benzothiazolyl ketones as 3CL<sup>pro</sup> inhibitors against SARS-CoV-2.

Project description:A series of peptidomimetic compounds containing benzothiazolyl ketone and [2.2.1] azabicyclic ring was designed, synthesized and evaluated in the hope of obtaining potent oral 3CLpro inhibitors with improved pharmacokinetic properties. Among the target compounds, 11b had the best enzymatic potency (IC50 = 0.110 μM) and 11e had the best microsomal stability (t1/2 > 120 min) and good enzyme activity (IC50 = 0.868 μM). Therefore, compounds 11b and 11e were chosen for further evaluation of pharmacokinetics in ICR mice. The results exhibited that the AUC(0-t) of 11e was 5143 h*ng/mL following single-dose oral administration of 20 mg/kg, and the F was 67.98%. Further structural modification was made to obtain compounds 11g-11j based on 11e. Among them, 11j exhibited the best enzyme inhibition activity against SARS-CoV-2 3CLpro (IC50 = 1.646 μM), the AUC(0-t) was 32473 h*ng/mL (20 mg/kg, po), and the F was 48.1%. In addition, 11j displayed significant anti-SARS-CoV-2 activity (EC50 = 0.18 μM) and low cytotoxicity (CC50 > 50 μM) in Vero E6 cells. All of the above results suggested that compound 11j was a promising lead compound in the development of oral 3CLpro inhibitors and deserved further research.

Synthesis of glutamic acid and glutamine peptides possessing a trifluoromethyl ketone group as SARS-CoV 3CL protease inhibitors.

Project description:Trifluoromethyl-β-amino alcohol 11 [(4S)-tert-butyl 4-amino-6,6,6-trifluoro-5-hydroxyhexanoate] was synthesized in five steps starting from Cbz-l-Glu-OH 5 where the key step involved the introduction of the trifluoromethyl (CF3) group to oxazolidinone 7, resulting in the formation of silyl ether 8 [(4S,5S)-benzyl 4-(2-(tert-butoxycarbonyl)ethyl)-5-(trifluoromethyl)-5-(trimethylsilyloxy)oxazolidine-3-carboxylate]. Compound 11 was then converted into four tri- and tetra-glutamic acid and glutamine peptides (1-4) possessing a CF3-ketone group that exhibited inhibitory activity against severe acute respiratory syndrome coronavirus protease (SARS-CoV 3CLpro).

Design, synthesis, and biological evaluation of novel dipeptide-type SARS-CoV 3CL protease inhibitors: structure-activity relationship study.

Project description:This work describes the design, synthesis, and evaluation of low-molecular weight peptidic SARS-CoV 3CL protease inhibitors. The inhibitors were designed based on the potent tripeptidic Z-Val-Leu-Ala(pyrrolidone-3-yl)-2-benzothiazole (8; Ki = 4.1 nM), in which the P3 valine unit was substituted with a variety of distinct moieties. The resulting series of dipeptide-type inhibitors displayed moderate to good inhibitory activities against 3CL(pro). In particular, compounds 26m and 26n exhibited good inhibitory activities with Ki values of 0.39 and 0.33 μM, respectively. These low-molecular weight compounds are attractive leads for the further development of potent peptidomimetic inhibitors with pharmaceutical profiles. Docking studies were performed to model the binding interaction of the compound 26m with the SARS-CoV 3CL protease. The preliminary SAR study of the peptidomimetic compounds with potent inhibitory activities revealed several structural features that boosted the inhibitory activity: (i) a benzothiazole warhead at the S1' position, (ii) a γ-lactam unit at the S1-position, (iii) an appropriately hydrophobic leucine moiety at the S2-position, and (iv) a hydrogen bond between the N-arylglycine unit and a backbone hydrogen bond donor at the S3-position.

Development of potent dipeptide-type SARS-CoV 3CL protease inhibitors with novel P3 scaffolds: design, synthesis, biological evaluation, and docking studies.

Project description:We report the design and synthesis of a series of dipeptide-type inhibitors with novel P3 scaffolds that display potent inhibitory activity against SARS-CoV 3CLpro. A docking study involving binding between the dipeptidic lead compound 4 and 3CLpro suggested the modification of a structurally flexible P3 N-(3-methoxyphenyl)glycine with various rigid P3 moieties in 4. The modifications led to the identification of several potent derivatives, including 5c-k and 5n with the inhibitory activities (Ki or IC50) in the submicromolar to nanomolar range. Compound 5h, in particular, displayed the most potent inhibitory activity, with a Ki value of 0.006 ?M. This potency was 65-fold higher than the potency of the lead compound 4 (Ki=0.39 ?M). In addition, the Ki value of 5h was in very good agreement with the binding affinity (16 nM) observed in isothermal titration calorimetry (ITC). A SAR study around the P3 group in the lead 4 led to the identification of a rigid indole-2-carbonyl unit as one of the best P3 moieties (5c). Further optimization showed that a methoxy substitution at the 4-position on the indole unit was highly favorable for enhancing the inhibitory potency.

Design and synthesis of new tripeptide-type SARS-CoV 3CL protease inhibitors containing an electrophilic arylketone moiety.

Project description:We describe here the design, synthesis and biological evaluation of a series of molecules toward the development of novel peptidomimetic inhibitors of SARS-CoV 3CL(pro). A docking study involving binding between the initial lead compound 1 and the SARS-CoV 3CL(pro) motivated the replacement of a thiazole with a benzothiazole unit as a warhead moiety at the P1' site. This modification led to the identification of more potent derivatives, including 2i, 2k, 2m, 2o, and 2p, with IC(50) or K(i) values in the submicromolar to nanomolar range. In particular, compounds 2i and 2p exhibited the most potent inhibitory activities, with K(i) values of 4.1 and 3.1 nM, respectively. The peptidomimetic compounds identified through this process are attractive leads for the development of potential therapeutic agents against SARS. The structural requirements of the peptidomimetics with potent inhibitory activities against SARS-CoV 3CL(pro) may be summarized as follows: (i) the presence of a benzothiazole warhead at the S1'-position; (ii) hydrogen bonding capabilities at the cyclic lactam of the S1-site; (iii) appropriate stereochemistry and hydrophobic moiety size at the S2-site and (iv) a unique folding conformation assumed by the phenoxyacetyl moiety at the S4-site.

Design, synthesis and in vitro evaluation of novel SARS-CoV-2 3CL<sup>pro</sup> covalent inhibitors.

Project description:Severe diseases such as the ongoing COVID-19 pandemic, as well as the previous SARS and MERS outbreaks, are the result of coronavirus infections and have demonstrated the urgent need for antiviral drugs to combat these deadly viruses. Due to its essential role in viral replication and function, 3CLpro (main coronaviruses cysteine-protease) has been identified as a promising target for the development of antiviral drugs. Previously reported SARS-CoV 3CLpro non-covalent inhibitors were used as a starting point for the development of covalent inhibitors of SARS-CoV-2 3CLpro. We report herein our efforts in the design and synthesis of submicromolar covalent inhibitors when the enzymatic activity of the viral protease was used as a screening platform.

Structure-based design, synthesis, and biological evaluation of peptidomimetic SARS-CoV 3CLpro inhibitors.

Project description:Structure-based design, synthesis, and biological evaluation of a series of peptidomimetic severe acute respiratory syndrome-coronavirus chymotrypsin-like protease inhibitors are described. These inhibitors were designed and synthesized based upon our X-ray crystal structure of inhibitor 1 bound to SARS-CoV 3CLpro. Incorporation of Boc-Ser as the P(4)-ligand resulted in enhanced SARS-CoV 3CLpro inhibitory activity. Structural analysis of the inhibitor-bound X-ray structure revealed high binding affinity toward the enzyme.
