352 Chemistry and Biology of Beta-Lactams
https://t.me/med1917
molecular mechanics was used in conjunction with the Merck molecular force eld (MMFF). All the
structures were made in 2D, and then they were converted into their respective 3D structures by using the
same software. To minimize their energy consumption, they were then analyzed using energy minimization procedures, followed by optimization using the MMFF software.
There is a variational method known as Hartree–Fock (HF) for determining the energy and wave
function of a quantum many-body system. HF is a variational method for nding the energy and wave
function. The Hartree–Fock approximation follows from the Schrödinger equation because it requires
that electrons are independent particles to represent Schrödinger equation. The geometric optimization
was performed using the 6-31G* basis sets after the energy minimization procedure was completed to
calculate the dipole moment.
The correlated models are the models that lessen the effects of the Hartree–Fock approximation on
the analysis. The models can be divided into two broad categories, density functional models and models based on wave functions. The density functional theory (DFT) is a mathematical model based on
quantum mechanics. A lot of work is done with this method to investigate the electronic structure (or
nuclear structure) of many-body systems, such as atoms, molecules, or condensed phases, in particular.
As of right now, the DFT has been viewed as the most effective and promising method for computing
a material’s electronic structure. Different basis sets can be used to make DFT calculations on different levels and at different levels of accuracy. The structures in this study are optimized after the energy
minimization procedure, employing the 6-31G* basis forms at the B3LYP level as a basis for optimizing
the structures. By doing this, a stereochemically stable structure for each compound can be obtained.
As a quantum chemistry post-Hartree–Fock–Fock ab initio method, the Møller–Plesset (MP) perturbation theory method is one of the most widely used quantum chemistry methods in the eld of
computational chemistry.

Compared to the Hartree–Fock method, the MP method improves on the
Hartree–Fock method by adding electron correlation effects to the equations using Rayleigh–Schrödinger
perturbation theory (RS-PT). For estimation of basic systems, second (MP2),
fourth (MP4)
118
order calculations are used. As part of the current work, the optimization of the 6-31G
116
th i rd ( M P3),
117
and
basis forms has been done at the MP2 level.
As a result of testing these optically active beta-lactams 1 and 2 against human cancer cell lines, we
found that their anticancer activity differed signicantly. A comparison of their anticancer activities is
given in Table 11.1. A total of seven human cancer cell lines were tested to conrm the results. Human
breast cancer cells are represented by MDA-231; human melanoma cells are represented by BRO; human
ovarian cancer cells are represented by SKOV-3; human colon cancer cells are represented by HT-29;
human prostate cancer cells are represented by PC-3; and human blood cancer cells are represented by
HL-60 and K-562. In Table 11.7, you will nd the values from cisplatin, which is a chemotherapy medicine used as a reference for the study.
In terms of the IC50 values for cell growth inhibition, it seems that the beta-lactams, (−)-1, demonstrate a signicant increase in activity against six human tumor lines when compared to cisplatin and
compound (+)-2. In addition, the results of this study showed that the activity of compound 1 is not uniform across all tumor lines, which suggests that the target of this compound’s action is highly specic.
It was found that compound 1 showed the greatest activity against the colon cancer cell line (HT-29) and
the blood cancer cell line (HL-60). Even though compound 2 showed activity against all seven human
cancer cell lines, the effect was not as strong as cisplatin or compound 1 when compared with each other.
To understand this activity difference between these two isomers, a computational molecular analysis is
the best method.
A growing amount of research is showing that organic molecules, particularly anticancer medicines
and candidates for drugs, have an important effect on the proteins in cells and their constituent components. There is a strong correlation between the electronic charges present in the drug molecules and the
tumor cells that accounts for the presence of these interactions. Using this well-known concept as a base,
it was a simple matter to calculate the dipole moment of the beta-lactams. As can be seen from Ta ble
11.8, the ground-state dipole moment values have been calculated for compounds 1 and 2. Five semiempirical methods (AM1, RM1, PM3, PM6, and MNDO) were used to calculate these values. According
to the results obtained, trans-beta-lactam 1 was observed to have a high value of dipole moment ranging
from 7. 13 D to 6.63 D. It was found that the value of the dipole moment for trans-beta-lactam 2 ranged

from 4.33 D to 5.11 D. Based on the comparison of other selected calculation methods, the MNDO analysis produced the smallest value for the dipole moment for the molecule. Nevertheless, a similar trend was
observed with compounds 1 and 2 as well.
Several quantum mechanical methods were used to conrm the dipole moment calculations, including
Hartree–Fock (HF), DFT, Møller–Plesset (MP), classical mechanics, and molecular mechanics (MM)
methods. Table 11.9 shows the results obtained. For purposes of comparison, the values obtained from
the AM1/semiempirical method were also included. There is no doubt that compound 1 has a higher
dipole moment than its chiral isomer 2 based on the results of the experiment. Based on a comparison
of MM with other selected methods for calculating the dipole moment, it was found that MM gave the
highest value. When compared to other methods, the MP method took more CPU time to complete the
calculation successfully compared to other methods.
There is no reason why optical isomers should differ in their dipole moment values, regardless of their
values. As it turns out, there are some differences in the values of dipole moments in the ve different
methods that have been used to calculate them.

FIGURE 11.12 The optimized geometry of β-lactam 1 and β-lactam 2 created using the DFT calculation.
There was a signicant difference between compound 1 and compound 2 in terms of its anticancer
activ it y. Figure 11.12 shows the optimized geometry of beta-lactam 1 and beta-lactam 2 that was created from the DFT calculations of the two beta-lactams. A dipole vector is presented by the arrows in
the gure. In the case of isomers, the direction of the dipole vector is distinct. It is important to point
out that the vector arrow on compound 2 does not exactly point at the oxygen atom in the beta-lactam
carbonyl group. Compound 1 on the other hand has its vector arrow pointing directly at a carbonyl group
on the beta-lactam ring in full, as opposed to compound 2. Based on the optimized structures of the two
compounds, we can see that there is a smaller distance between the phenyl group at C4 and the acetoxy
group at C3 in compound 1 than in compound 2.
Several other physicochemical parameters that are important for the calculation of structure–activity relationships (SARs), structure–property–activity relationships (SPARs), and quantitative structure–
activity relationships (QSARs) have also been calculated. It was necessary to perform three different
calculation methods to check the validity of the data, such as the DFT method, Hartree–Fock (HF)
method, and Möller–Plesset (MP) method. The physicochemical and molecular properties of the mol-
ecules such as molecular weight, total energy, solvation energy, energy of the highest occupied molecular orbital (E HOMO), energy of the lowest unoccupied molecular orbital (E LUMO), polarizability,
octanol–water partition coefcient (Log P), polar surface area (PSA), number of hydrogen bond donors
(HBDs), number of hydrogen bond acceptors (HBAs), surface area, volume of the molecule, and ovality
were all measured. Table 11.10 shows the results obtained.

355The Effects of Dipole Moments on the Biological Activities of Diverse Beta-Lactams
It can be observed from Ta ble 11.10 that most of the considered physicochemical and structural parameters for compound 1 and compound 2 are the same. There is very little variation observed in the E
LUMO, E HOMO, area, volume, and PSA parameters. It is interesting to note that all of the calculation
methods show the same trend. Compared to the dipole moment, these parameters have a much smaller
effect on controlling the bioactivity of the compound.
The reactivity descriptors such as energy gap (ΔE) ionization potential (I), electron afnity (A), electronegativity (χ), global hardness (η), softness (σ), chemical potential (μ), and global electrophilicity
index (ω) were also calculated at the B3LYP/6-31G* level of theory. Table 11.11 lists the obtained values.
It was found that the values of both compounds were comparable.
A number of useful graphical models were also analyzed, such as local ionization potentials, LUMO
maps, and electrostatic potentials, that provided insights into the electron density, nucleophile regions,
and electrophile regions of the molecules.
As far as domain maps of properties are concerned, the electrostatic potential map is the most commonly used and the most important. The charge distribution in a molecule can be determined by using
this indicator. A molecule’s electrostatic potential map is employed as a tool to determine its chemical
reactivity according to its reactivity map. The importance of this graphical analysis is that it allows the
identication of the reactive sites of nucleophilic or electrophilic attack in hydrogen bonding interactions, as well as the understanding of how biological recognition occurs. Figure 11.13 presents a map of

the electrostatic potentials of beta-lactam isomers. The blue region of the diagram presents the highest
positive potential, the red region presents the highest electron density and the negative potential, and the
green region presents the neutral electrostatic potential. Figure 11.13 shows that both compounds have
hydrophobic (neutral) regions and hydrophilic (positive and negative potentials) regions and are comparable in their electrostatic potential maps.
A maximum value of −273.80 kJ/mol can be found for the negative electrostatic potential of compound
1, and a maximum value of 136.72 kJ/mol can be found for the positive electrostatic potential of compound 1. Compound 2 presents a maximum negative electrostatic potential of −284.61 kJ/mol, whereas
its positive electrostatic potential is 134.52 kJ/mol.
It is necessary to map the local ionization potential onto a size surface, to determine the region from
which electrons are most easily ionized. Fig u re 11.14 shows the maps of the local ionization potentials of
the compounds. Also, in terms of electrophilic reactions, the ionization potential can be used as a tool to
assess chemical reactivity and selectivity. It can be seen that this overlay represents the energy required
to remove electrons (ionization) on the density of electrons. In the case of molecule 1, the energy ranges

FIGURE 11.15 LUMO map of compounds 1 and 2.
from 13.74 eV to 42.94 eV; in the case of molecule 2, the energy ranges from 12.99 eV to 43.39 eV. As far
as the map and energy range values are concerned, there have been no variations observed.
In Fig u r e 11.15, a schematic diagram illustrating the LUMO maps of beta-lactam isomers is shown.
In its simplest form, a LUMO map is a way of identifying the sites on a molecule that are most electron
decient, that is, the sites that are most likely to be attacked by nucleophiles. As such, it can be used to
indicate nucleophilic addition, since it is derived from an overlay of the absolute value of the LUMO on
the density of electron of the molecule. According to the map, it appears that both of the LUMO maps
for the two compounds are identical. There is once again conrmation that all of the compounds have
the same LUMO energy. Colors toward red show low (close zero) LUMO values.
The physicochemical and geometrical parameters such as total energy, weight, dipole moment, solvation energy, energy gap (ΔE), E LUMO, E HOMO, polarizability, Log P, HBD, PSA, HBA, volume of
the molecule, surface area, ovality, electron afnity (A), ionization potential (I), global hardness (η),
electronegativity (χ), softness (σ), global electrophilicity index (ω), and chemical potential (μ) of opti-
cally active beta-lactams were calculated in this work. Likely, such an exploratory study of optically
active trans-enantiomeric beta-lactams and their anticancer activity has never been conducted before.
This makes this study unique. To verify the data, several graphical quantities have also been analyzed,
including local ionization potential, LUMO maps, and electrostatic potential.
11.6 Conclusion
The importance of dipole moment in determining the biological activity of diverse beta-lactams is discussed in this chapter. It was found that in many of the compounds, the dipole moment correlated directly
with the biological activity.
