Abstract
In the context of the global health issue caused by the growing occurrence of antimicrobial resistance (AMR), the need for novel antimicrobial agents is becoming alarming. Inorganic and organometallic complexes represent a relatively untapped source of antibiotics. Here, we report a computer-aided drug design (CADD) based on a 'scaffold-hopping' approach for the synthesis and antibacterial evaluation of fac-Re(I) tricarbonyl complexes bearing clotrimazole (ctz) as a monodentate ligand. The prepared molecules were selected following a pre-screening in silico analysis according to modification of the 2,2'-bipyridine (bpy) ligand in the coordination sphere of the complexes. CADD pointed to chiral 4,5-pinene and 5,6-pinene bipyridine derivatives as the most promising candidates. The corresponding complexes were synthesized, tested toward methicillin-sensitive and -resistant S. aureus strains, and the obtained results evaluated with regard to their binding affinity with a homology model of the S. aureus MurG enzyme. Overall, the title species revealed very similar minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values as those of the reference compound used as the scaffold in our approach. The obtained docking scores advocate the viability of 'scaffold-hopping' for de novo design, a potential strategy for more cost- and time-efficient discovery of new antibiotics.

Abstract
Organophosphorus ligands are an invaluable family of compounds that continue to underpin important roles in disciplines such as coordination chemistry and catalysis. Their success can routinely be traced back to facile tuneability thus enabling a high degree of control over, for example, electronic and steric properties. Diphosphines, phosphorus compounds bearing two separated PIII donor atoms, are also highly valued and impart their own unique features, for example excellent chelating properties upon metal complexation. In many classical ligands of this type, the backbone connectivity has been based on all carbon spacers only but there is growing interest in embedding other donor atoms such as additional nitrogen (–NH–, –NR–) sites. This review will collate some important examples of ligands in this field, illustrate their role as ligands in coordination chemistry and highlight some of their reactivities and applications. It will be shown that incorporation of a nitrogen-based group can impart unusual reactivities and important catalytic applications.

Abstract
![]()
N-Triphos derivatives
(NP3R, R = alkyl, aryl)
and asymmetric variants (NP2RXR′, R′ = alkyl, aryl, X = OH, NR2, NRR′) are
an underexplored class of tuneable, tripodal ligands in relation to
the coordination chemistry of Re and Tc for biomedical applications.
Mixed-ligand approaches are a flexible synthetic route to obtain Tc
complexes of differing core structures and physicochemical properties.
Reaction of the NP3Ph ligand with the Re(V)
oxo precursor [ReOCl3(PPh3)2] generated
the bidentate complex [ReOCl3(κ2-NP2PhOHAr)], which possesses an unusual
AA’BB’XX’ spin system with a characteristic second-order
NMR lineshape that is sensitive to the bi- or tridentate nature of
the coordinating diphosphine unit. The use of the asymmetric NP2PhOHAr ligand resulted in the formation
of both bidentate and tridentate products depending on the presence
of base. The tridentate Re(V) complex [ReOCl2(κ3-NP2PhOAr)] has provided
the basis of a new reactive “metal-fragment” for further
functionalization in [3 + 2] mixed-ligand complexes. The synthesis
of [3 + 2] complexes with catechol-based π-donors could also
be achieved under one-pot, single-step conditions from Re(V) oxo precursors.
Analogous complexes can also be synthesized from suitable 99Tc(V) precursors, and these complexes have been shown to exhibit
highly similar structural properties through spectroscopic and chromatographic
analysis. However, a tendency for the {MVO}3+ core to undergo hydrolysis to the {MVO2}+ core has been observed both in the case of M = Re and markedly
for M = 99Tc complexes. It is likely that controlling this
pathway will be critical to the generation of further stable Tc(V)
derivatives. An N-centered tripodal heterofunctionalized
phosphine ligand
was used to generate a reactive “metal-fragment” based
on the {MVO}3+ (M = Re, 99Tc) core
for the formation of mixed-ligand [3 + 2] complexes. Characteristic
lineshapes arising from an AA’BB’XX’ spin system
are diagnostic of bidentate vs tridentate coordination modes of the
ligand.
