Exploring 2-methyl-substituted vitamin K 3 derivatives with potent inhibitory activity against the 3CL protease of SARS-CoV-2. Bioorg Med Chem Lett 2024; 100:129642. [PMID: 38310976 DOI: 10.1016/j.bmcl.2024.129642] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 01/19/2024] [Accepted: 01/30/2024] [Indexed: 02/06/2024]
Abstract
Since the outbreak of the pandemic, various anti-SARS-CoV-2 drugs have been developed. In particular, 3CL protease (3C-like protease, 3CLpro) is an attractive drug target because it is an essential enzyme for viral multiplication and is present only in viruses, not in humans. To date, 3CLpro inhibitors against SARS-CoV-2 such as nirmatrelvir and ensitrelvir have been launched as oral drugs in Japan, but there is still no potent drug against SARS-CoV-2, due to issues of in vivo absorption and stability. Recently, vitamin K3 was reported to show inhibitory activity against 3CLpro of SARS-CoV-2, and the mechanism of action was predicted to be the formation of a covalent bond between the thiol group of cysteine 145, the active center of 3CLpro, and the C-3 position of vitamin K3. Therefore, we synthesized derivatives in which the 2-methyl group of the vitamin K3 was systematically converted to other substituents and examined their inhibitory activity against 3CLpro of SARS-CoV-2. The results showed that the compounds with the sulfide structure showed an approximately 4-fold increase in activity over vitamin K3. These results indicated the possibility of creating new inhibitors based on vitamin K3 and its derivatives.

Abstract
Pancreatic tumors grow in an "austerity" tumor microenvironment characterized by nutrient deprivation and hypoxia. This leads to the activation of adaptive pathways in pancreatic cancer cells, promoting tolerance to nutrition starvation and aggressive malignancy. Conventional anticancer drugs are often ineffective against tumors that grow in such austerity condition. Plumbagin, a plant-derived naphthoquinone, has shown potent preferential cytotoxicity against pancreatic cancer cells under nutrient-deprived conditions. Therefore, we synthesized a series of plumbagin derivatives and found that 2-(cyclohexylmethyl)-plumbagin (3f) was the most promising compound with a PC50 value of 0.11 μM. Mechanistically, 3f was found to inhibit the PI3K/Akt/mTOR signaling pathways, leading to cancer cell death under nutrient-deprived conditions. In vivo studies using pancreatic cancer xenograft mouse models confirmed the efficacy of 3f, demonstrating significant inhibition of tumor growth in a dose-dependent manner. Compound 3f represents a highly promising lead for anticancer drug development based on an antiausterity strategy.

Abstract
An organocatalytic enantioselective epoxidation of 2,3-disubstituted naphthoquinones with tert-butyl hydroperoxide as an oxidant was developed using a guanidine-urea bifunctional catalyst lacking C2 symmetry, which was designed based upon the insights obtained from the DFT calculation model for our previous C2 symmetric catalyst. The present organocatalytic reaction provides access to a variety of optically active naphthoquinone epoxides bearing aryl and methyl substituents at C2 and C3 in high yields with high enantioselectivities (up to 97:3 er).

Abstract
Background NAD(H/+) and NADP(H/+) are the most important redox cofactors in bacteria. However, the intracellular redox balance is in advantage of the cell growth and production of NAD(P)H-dependent products. Results In this paper, we rationally engineered glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and isocitrate dehydrogenase (IDH) to switch the nucleotide-cofactor specificity resulting in an increase in final titer [from 85.6 to 121.4 g L−1] and carbon yield [from 0.33 to 0.46 g (g glucose)−1] of l-lysine in strain RGI in fed-batch fermentation. To do this, we firstly analyzed the production performance of original strain JL-6, indicating that the imbalance of intracellular redox was the limiting factor for l-lysine production. Subsequently, we modified the native GAPDH and indicated that recombinant strain RG with nonnative NADP-GAPDH dramatically changed the intracellular levels of NADH and NADPH. However, l-lysine production did not significantly increase because cell growth was harmed at low NADH level. Lastly, the nonnative NAD-IDH was introduced in strain RG to increase the NADH availability and to equilibrate the intracellular redox. The resulted strain RGI showed the stable ratio of NADPH/NADH at about 1.00, which in turn improved cell growth (μmax. = 0.31 h−1) and l-lysine productivity (qLys, max. = 0.53 g g−1 h−1) as compared with strain RG (μmax. = 0.14 h−1 and qLys, max. = 0.42 g g−1 h−1). Conclusions This is the first report of balancing the intracellular redox state by switching the nucleotide-cofactor specificity of GAPDH and IDH, thereby improving cell growth and l-lysine production.![]() Electronic supplementary material The online version of this article (10.1186/s12934-019-1114-0) contains supplementary material, which is available to authorized users.
