Among the halogen substituents at position 4 of the phenyl ring within D - Phe2, fluorine showed to be optimal, since chlorine and bromine, or even a nitro group, negatively affected the activity profile of 26, 27, 28 and 29 (IC50 = 0.035, 0.79, 0.57 and 0.94 μM, respectively).

When the amino acid was added in the para position of the phenyl substituent, the overpotential was much higher than when it was added in the meta position.

Frontier electron density at the ether oxygen position and superdelocalizability at the ortho position show good parallelism with biological activity — that is, the stimulant activity of phenyl ether choline molecules.

SAR studies indicated that the central aromatic ring is crucial for high CXCR4 affinity, and that a one - carbon separation between the central aromatic phenyl ring and the nitrogen of the acyclic linker is strictly required for potency.

Using reference samples of TPCO 5,5» - bis (4 -(trimethylsilyl) phenyl)-2,2» - bithiophene (TMS - PTTP - TMS) crystals doped with a longer TPCO 5,5»» - bis (4 -(trimethylsilyl) phenyl)-2,2»: 5», 2»: 5», 2»» - quaterthiophene (TMS - PTTTTP - TMS) and assuming, that the absorption is linearly dependent on the impurity concentration, we can estimate the impurity concentration in other similar samples.

On the other hand, in order to reduce the basicity of the amine, addition of electron withdrawing groups on the phenyl ring, such as F (e.g. 132) and CF3 (e.g. 133), led to compounds with high absorption potentials, but, with a concomitant loss of antiviral activity.

Subsequently, the order of preferred positions of fluorine on the phenyl ring of D - Phe1 was determined to be as ortho, meta, para (22 > 23 > 16; IC50 = 0.059, 0.088 and 0.22 μM, respectively).

The team prepared two gold cluster solutions that differed only in the substitution of either cyclohexane groups or phenyl groups at the phosphorus centers of diphosphine ligands.

In addition, gold clusters with the phenyl - containing ligand fragmented through a wide range of dissociation channels involving the loss of gold atoms as well as activation of the phosphorus - carbon bonds of the ligands.

Furthermore, theoretical calculations on diphosphine capped gold clusters often involve the substitution of simpler hydrogen atoms in the place of computationally demanding substituents such as phenyl groups with the assumption that the substitution does not alter the stability of the cluster.

Methods: Diphenylphosphine ligands, which consist of two phenyl (C6H5) substituted phosphorus centers separated by a carbon chain of variable length, produce gold clusters with extremely narrow distributions in size; that is, the synthesis route produces a large quantity of clusters with the same number of gold atoms as well as a small number of clusters with similar numbers of atoms.

In contrast, the substituents (e.g., phenyl (C6H5)-RRB- at the two phosphorus centers are generally regarded as not exerting an influence on the selectivity of diphosphine ligands towards gold clusters of a particular size.
