Opportunistic infections from pathogenic fungi present a major challenge to healthcare because of a very limited arsenal of antifungal drugs, an increasing population of immunosuppressed patients, and increased prevalence of resistant clinical strains due to overuse of the few available antifungals. Cryptococcal meningitis is a life-threatening opportunistic fungal infection caused by one of two species in the Cryptococcus genus, Cryptococcus neoformans and Cryptococcus gattii. Eighty percent of cryptococcosis diseases are caused by C. neoformans that is endemic in the environment. The standard of care is limited to old antifungals, and under a high standard of care, mortality remains between 10 and 30%. We have identified a series of 5-nitro-6-thiocyanatopyrimidine antifungal drug candidates using in vitro and computational machine learning approaches. These compounds can inhibit C. neoformans growth at submicromolar levels, are effective against fluconazole-resistant C. neoformans and a clinical strain of C. gattii, and are not antagonistic with currently approved antifungals.

The NO-sGC-cGMP signaling pathway plays an important role in the cardiovascular system. Loss of nitric oxide tone or impaired signaling has been associated with cardiovascular diseases, such as hypertension, pulmonary hypertension and heart failure. Direct activation of sGC enzyme independent of NO represents a novel approach for modulating NO signaling with tremendous therapeutic potential. Herein, we describe the design of a structurally novel class of heme-dependent sGC stimulators containing the 3,3-dimethylpyrrolidin-2-one moiety which resulted in the identification of the potent, selective stimulator 30 (MK-2947) for the treatment of hypertension.
Synthesis of ticagrelor analogues belonging to 1,2,3-triazolo[4,5-d]pyrimidines and study of their antiplatelet and antibacterial activity

Based on the recent observation that the antiplatelet agent ticagrelor and one of its metabolite exert bactericidal activity against gram-positive bacteria, a series of 1,2,3-triazolo[4,5-d]pyrimidines structurally related to ticagrelor were synthesized and examined as putative antiplatelet and antibacterial agents. The aim was to assess the possibility of dissociating the two biological properties and to find novel 1,2,3-triazolo[4,5-d]pyrimidines expressing antiplatelet activity and devoid of in vitro antibacterial activity. The new compounds synthesized were known metabolites of ticagrelor as well as structurally simplified analogues. Some of them were found to express antiplatelet activity and to lose the antibacterial activity, supporting the view that the two activities were not necessarily linked.

Paragraph 0014-0016, (2019/11/12)
The invention provides a synthetic method of 2-methylmercapto-4,6-dichloro-5-nitropyrimidine. The synthetic method comprises the following steps that 2-methylmercapto-4,6-dihydroxypyrimidine are addedinto nitrosonitric acid in batches, stirring is conducted at the room temperature for 1 h, reaction is conducted by heating; after reaction is completed, the temperature is lowered to the room temperature, the mixture is slowly poured into ice water and stirred for 1 h, filtering is conduced, a filter cake is washed till neutral and dug out to be dried, and a compound B is obtained; the compoundB, phosphorus oxychloride and the organic alkali are mixed for chlorination; after completion, the mixture is cooled, the extra phosphorus oxychloride are removed through vacuum concentration, after water is added for quenching, an organic solvent is used for extraction, drying and concentration are conducted, and a pure product is obtained. According to the synthetic method of the 2-methylmercapto-4,6-dichloro-5-nitropyrimidine, nitrification and chlorination are conducted on raw materials which are available in the market to generate the pure product; the raw materials are supplied by largecommercial supply, and are cheap and easy to obtain, auxiliary materials can be recycled and reused, the cost is obviously lowered, meanwhile, pollution on the environment of toxic substance in the production process is avoided, and safety in the operation process is improved; and the yield is greatly improved, the time is effectively shortened, operation is easy, and the post treatment process issimplified.

An efficient and convenient approach for the preparation of functionalized 2-(methylsulfonyl)pyrimidine derivatives has been developed through cyclic condensation of malonate derivatives with S-methylisothiouronium sulfate followed by derivation and oxidation in water–acetone mixture using oxone as the oxidant. This synthetic strategy provides an efficient and environmentally friendly approach for easy access to 2-(methylsulfonyl)pyrimidine derivatives with considerable yields.
