Abstract: A Sociedade Brasileira de Química comemorou seus 25 anos em sua 25ª Reunião Anual, que mais do que nunca foi plenamente exitosa. A excelente participação de nossa Comunidade nesta reunião foi ponto de destaque, coroando os esforços realizados pela Comissão Organizadora para que tivéssemos uma RA vivamente comemorativa, sem distanciarmos de nosso referencial acadêmico-científico. Considero completamente alcançado este objetivo. Missão cumprida! É necessário e prazeiroso sublinhar os mais profundos agradecimento… Show more

“…The strategy of molecular simplification on pyridazinone phosphodiesterase (PDE) inhibitors (1) [4], represented by a simple bond rupture in a and the elimination of the stereogenic center in b, enabled us to recognize the structural similarity between N-acylhydrazone (NAH) derivatives (2) and these cardioactive compounds [5]. The inclusion of the 1,3-benzodioxolyl ring, coming from Brazilian natural safrole (3) [6] attached to the acyl group of NAH moiety [7,8] and replacing the phenyl ring attached to the imine moiety by the bioisosteric 2-thienyl ring [9] resulted in the design of 3,4-methylenedioxybenzoyl-2-thienyl-hydrazone, named LASSBio-294 (4) (Chart 1) [5].…”

“…To optimize the structure of compound 3 a, which showed better IC 50 and SI values, we carried out the synthesis of three other derivatives. The three new derivatives of 3 a were designed by bioisosterism [49] and molecular simplification [50] strategies (Scheme 3). Bioisosterism was applied in the design of compounds 5 and 7.…”
