The first Dirichlet eigenvalue of bicyclic graphs [PDF]

open access: yes, 2012
summary:In this paper, we have investigated some properties of the first Dirichlet eigenvalue of a bicyclic graph with boundary condition. These results can be used to characterize the extremal bicyclic graphs with the smallest first Dirichlet eigenvalue

Computer-aided design, synthesis, and biological evaluation of [4.3.0] bicyclic prolyl oligopeptidase and fibroblast activation protein-α dual inhibitors

open access: yes, 2021
We have previously described several different chemical series of bicyclic prolyl oligopeptidase (POP) inhibitors as probes for neurodegenerative diseases that demonstrated nanomolar activity in vitro and submicromolar activity in cellulo.

Chemistry Teacher Trainees’ use of Molecular Models in Learning Spiro and Bicyclic Compounds

open access: yesScience Education International, 2022
The study diagnosed chemistry teacher trainees’ difficulties in naming and writing structures of spiro and bicyclic compounds. The case study design was conducted in a constructivist environment to enhance chemistry teacher trainees’ ability to construct,

Ring-opening metathesis of some strained bicyclic systems; stereocontrolled access to diolefinated saturated heterocycles with multiple stereogenic centers

open access: yesBeilstein Journal of Organic Chemistry, 2018
Ring-opening metathesis (ROM) of various unsaturated, constrained bicyclic ring systems has been investigated with the use of commercial ruthenium-based catalysts. Starting from various cyclodienes, the corresponding derived bicyclic lactone, lactam, and

A practical preparation of bicyclic boronates via metal-free heteroatom-directed alkenyl sp 2-C‒H borylation

open access: yesCommunications Chemistry, 2023
Bicyclic boronates play critical roles in the discovery of functional materials and antibacterial agents, especially against deadly bacterial pathogens. Their practical and convenient preparation is in high demand but with great challenge.

Generalized bicycles

open access: yesDiscrete Applied Mathematics, 1997
Let \(G=(V,E)\) be a graph with \(n\) vertices, and let \(M\) be a (left) modul over a principal ideal domain \(D\). Let \(W_0(M)\) and \(W_1(M)\) denote the modules of all vertex and edge weightings over \(M\), respectively. An incidence weighting \(\eta\) of \(G\) is a weighting of each incident vertex-edge pair \((v, e)\) with an element of \(D ...

Bridged Bicyclic Building Block Upgrading: Photochemical Synthesis of bicyclo[3.1.1]heptan-1-Amines

open access: yes, 2020
Compounds containing bridged bicyclic carbon skeletons are desirable building blocks for medicinal chemistry. However, as a result of their inefficient, linear syntheses, commercially available compounds of this sort are plagued by high costs and/or a ...

On the inverse mostar index problem for molecular graphs [PDF]

open access: yesTransactions on Combinatorics
Mostar indices are recently proposed distance-based graph invariants, that already have been much investigated and found applications. In this paper, we investigate the inverse problem for Mostar indices of unicyclic and bicyclic molecular graphs.
