In the crystal structure of the title compound, C(28)H(37)N(4)O(2)S(+)·Cl(-) [systematic name: 4-(1,2-benzothia-zol-3-yl)-1-({2-[(3,5-dioxo-4-aza-tricyclo-[5.2.1.0(2,6)]decan-4-yl)meth-yl]cyclo-hex-yl}meth-yl)piperazin-1-ium chloride], the anions and cations are linked by N-H⋯Cl hydrogen bonds. The crystal structure is further stabilized by C-H⋯π and C-H⋯O inter-actions.

A new vocabulary item has been added to English dictionaries: Covid-19. For linguists, the addition of a meaningful linguistic element to any language should change the whole language as, for T. S. Eliot, a new poem changes the whole literature of a nation. But let us see how seriously the addition of the vocabulary item Covid-19 might change the English language. According to Cambridge online ...

Phosphonated isoxazolinyl nucleosides have been prepared via 1,3-dipolar cycloaddition reaction of nitrile oxides with corresponding vinyl or allyl nucleobases for antiviral studies. The cytotoxicity, the anti-HSV activity and the RT-inhibitory activity of the obtained compounds were evaluated and compared with those of AZT and diethyl{(1'SR,4'RS)-1'-[[(5-methyl-2,4-dioxo-3,4-dihydropyrimidin-1...

In the crystal structure of the title compound, C(8)H(6)N(2)O(3), the mol-ecules are linked by a pairs of inter-molecular N-H⋯O hydrogen bonds, forming inversion dimers. The aldehyde group is in the same plane as the pyrimidine ring [with a maximum deviation of 0.083 (2) Å for the O atom), and the linear propargyl group [C-C-C = 178.99 (19)°] makes a dihedral angle of 74.36 (13)° with the ring.
