Amidines with a trichloromethyl group exhibit the properties of inotropic agents, which are used as scaffolds in synthesizing aza-hete­rocycles and ligands for complex formation. Functionalized amidines show anticancer, antidiabetic activity, antihypertensive antiparasitic agents. The synthesis new functional derivatives such is definitely an urgent task. introduction alkenyl substituent severa...

Gaffkya homari, a micrococcus isolated from septicemic lobsters, has an obligate purine requirement (Aaronson, 1956). Further study shows this requirement to be satisfied by several natural purines as well as by several purine analogues. This broad response suggested that G. homari might be useful for studying purine biosynthesis. We wished especially to know whether G. homari utilized 4-amino-...

A novel benzopyrano[4,3-d]pyrimidine scaffold was generated via a three-component one-pot reaction from iodochromone, alkyne, and an amidine through a Sonogashira coupling, condensation, and cycloaddition. This combinatorial synthetic approach provides an efficient, easy construction of a diversified heterocyclic compounds library.

The ability of Boophilus microplus strains to be susceptible (-) or resistant (+) to amidines (Am), synthetic pyrethroids (SP), and/or organo-phosphates (OP) (or acaricide profiles) was investigated in 217 southeastern Mexican cattle ranches (located in the states of Yucatán, Quintana Roo, and Tabasco). Three questions were asked: (1) whether acaricide profiles varied at random and, if not, whi...

The title amidine compound, C14H20N2, prepared by a one-pot reaction, is asymmetric as only one N atom has an alkyl substituent. The terminal cyclo-hexyl group connected to the amino N atom is located on the other side of the N-C-N skeleton to the 4-methylbenzene ring and has a chair conformation. The dihedral angle between the phenyl ring and the NCN plane is 47.87 (12)°. In the crystal, mol-e...
