Paragraph 0045; 0048; 0053-0054, (2021/12/07)
The invention discloses application of myrtle ketone compounds in preparation of novel coronavirus SARS-CoV-2 medicaments. The myrtle ketone compound has obvious inhibition effect on novel coronavirus SARS-CoV-2. Mechanisms include, but are not limited to, inhibition of new coronavirus SARS-CoV-2 into cells, preventing the replication of new coronavirus SARS-CoV-2 in the host cell, and timely modulating apoptosis of infected cells. To the myrtle ketone compound provided by the invention, the novel coronavirus SARS-CoV-2 has a remarkable inhibiting effect, and the cytotoxicity is relatively small. It can therefore be used for the prophylaxis or treatment of neoplastic pneumonitis. The invention is expected to provide new candidate drug molecules for clinic treatment of nebrodensis.

Paragraph 0049-0052; 0057-0058, (2021/12/07)
The present invention discloses myrtle ketone compounds and their applications in the preparation of anti-influenza virus drugs. The myrtle ketone compounds of the present invention have a significant inhibitory effect on influenza viruses, the mechanism of action of which includes (but is not limited to) inhibiting influenza viruses entering cells, preventing the replication of influenza viruses in host cells, and timely regulating the apoptosis program of infected cells. The myrtle ketone compounds provided by the present invention have inhibitory effects on both influenza A and B viruses, the activity is better than the positive drug ribavirin (Ribavrin), and therefore can be used to prevent or treat influenza. The present invention is expected to provide a new active lead compound or drug candidate molecule for the clinical treatment of influenza.

The first biomimetic total syntheses of three biologically meaningful acylphloroglucinols, watsonianones A and B and corymbone B, with potent antiplasmodial activity, were performed. Their total syntheses were carried out through a diversity-oriented synthetic strategy from congener 2,2,4,4-tetramethyl-6-(3-methylbutylidene)cyclohexane-1,3,5-trione with high step efficiency. The spontaneous enolization/air oxidation of the precursor 2,2,4,4-tetramethyl-6-(3-methylbutylidene)cyclohexane-1,3,5-trione through a singlet O2-induced Diels-Alder reaction pathway to assemble the key biosynthetic peroxide intermediate is also discussed.

Rhodomyrtusials A–C, the first examples of triketone-sesquiterpene meroterpenoids featuring a unique 6/5/5/9/4 fused pentacyclic ring system were isolated from Rhodomyrtus tomentosa, along with several biogenetically-related dihydropyran isomers. Two bis-furans and one dihydropyran isomer showed acetylcholinesterase (AChE) inhibitory activity. Structures of the isolates were unambiguously established by a combination of spectroscopic data, ECD analysis, and total synthesis. Bioinspired total syntheses of six isolates were achieved in six steps utilizing a reactive enetrione intermediate generated in situ from a readily available hydroxy-endoperoxide precursor.
