A photochemical cascade process is reported affording complex pentacyclic scaffolds in high yields from readily available substrates. Flow processing provided reaction control and scalability to generate gram quantities of these intriguing for further studies.

the first ($pi_1$) and the second $(pi_2$) multiplicative zagreb indices of a connected graph $g$, with vertex set $v(g)$ and edge set $e(g)$, are defined as $pi_1(g) = prod_{u in v(g)} {d_u}^2$ and $pi_2(g) = prod_{uv in e(g)} {d_u}d_{v}$, respectively, where ${d_u}$ denotes the degree of the vertex $u$. in this paper we present a simple approach to order these indices for connected graphs on ...

Sweet basil (Ocimum basilicum) is well known for its diverse pharmacological properties and has been widely used in traditional medicine for the treatment of various ailments. Although a variety of secondary metabolites with potent biological activities are identified, our understanding of the biosynthetic pathways that produce them has remained largely incomplete. We studied transcriptional ch...

a graph is textit{symmetric}, if its automorphism group is transitive on the set of its arcs. in this paper, we  classifyall the connected cubic symmetric  graphs of order $36p$  and $36p^{2}$, for each prime $p$, of which the proof depends on the classification of finite simple groups.

Decoctions, macerations and fumigations of the stem bark and wood of Terminalia brownii 20 Fresen. are used in traditional medicine for fungal infections and as pesticides on field crops and in 21 traditional granaries in Sudan. In addition, T. brownii is commonly used for protecting wooden 22 houses and furniture. Therefore, using agar disc diffusion and macrodilution methods, eight extracts 2...
