In this study, the drug combination of 1-cyclohexyl-1-phenyl-3-pyrrolidin-1-yl-propan-1-ol hydrochloride or Procychelidine was applied on fullerene and its dual halogen derivatives were optimized in the position of carbon 62. In this study, using initial computation methods, the rate of participation of atomic orbitals and hybrid coefficients in adjacent adjacent atoms was calculated, and the Procyclidine 2X-C60 composition was studied by varying substitutions such as Br, Cl, F. The results indicate the change in the rate of orbital participation and the degree of sustainability affected by these changes in this link.

In this study, high energy energy derivatives of TEX with different carbon-containing fullerenes at different temperature conditions were studied using density functional theory. For this purpose, the materials were first geometric optimized, then the thermodynamic parameters were calculated for all of them. Then, the process of changing the energy-dependent parameters such as specific heat capacity, enthalpy, entropy and Gibbs free energy relative to molecular mass, molecular volume and measured level in this study at a given temperature, were evaluated against each other.

In this study, the combination of Phenergan C17H2ON2S, in which two aromatic rings are present, are attached to the rings at carbon position 5 and 13 halogens, and the changes in the asymmetric parameter, the convex constants, and the chemical displacement of the lateral carbon atoms are calculated. It shows that with the change of halogen based on the electronegativity of the fluorine atom, the contiguous constants always have the lowest values and chemical displacement in most of the carbon atoms studied.

Tetryzoline(TH) is an adrenergic agent (vasoconstrictors) and derived from imidazoline. This compound is closely related to naphazoline hydrochloride in its pharmacological action. Nanotechnology has been used to provide advanced biomedical research tools in drug delivery. The fullerene family especially C60 derivatives have appealing photo-, electro-chemical and physical properties for biomedical applications. In this report, at the first Tetryzoline drug located on fullerene and halogen derivatives (in carbon position 69) [C60- Tetryzoline – C69-X] (X=F, Cl, Br) were optimized. Then the calculation of natural bond orbital was performed with the NBO technique. All calculations using Hartree- Fock the 6-31G * basis set using Gaussian 98 software and in gas phase has been done. The results showed that the energy levels of molecular orbitals (HOMO & LUMO) in the R-F have the lowest value. C69-F is shortest bond and most Strength. Comparison of the dipole moment of compounds shows this trend: R-F> R-Cl> R-Br.

A fullerene is any molecule composed entirely of carbon, in the form of a hollow sphere.Naphazoline is a sympathomimetic agent with marked alpha adrenergic activity. It is a vasoconstrictor with a rapid action in reducing swelling when applied to mucous membrane. It acts on alpha-receptors in the arterioles of the conjunctiva to produce constriction, resulting in decreased congestion. It is an active ingredient in several over-the-counter formulations including Clear Eyes and Naphcon eye drops.In this research work at The first compounds [C60-Nafazolin-Cn-2X]+ and [Nafazolin-Cn-2X]+ (X=F,Cl,Br) were optimized. Then the calculation of natural bond orbitals was performed with the NBO technique. All calculations using Hartree- fock the 6-31G * basis set using Gaussian 98 software and in gas phase has been done. The results showed that the energy levels of molecular orbital (HOMO & LUMO) in the RF has the lowest value. C65-X has a length of the shortest bond and the bond has most power. Comparison of the dipole moments of compounds shows this trend: RF> R-Cl> R-Br but to be noticed that with same trend in nano carrier dipole moment is reducing. The values of Charge transfer energy for σ σ* (C7 - X26 C5 - N6 ) show this order R-Br> R-Cl > R-F

Oxymetazoline is a decongestant. It works by constricting (shrinking) blood vessels (veins and arteries) in your body. The nasal formulation acts directly on the blood vessels in your nasal tissues. Constriction of the blood vessels in your nose and sinuses leads to drainage of these areas and a decrease in congestion. Oxymetazoline is an adrenomimetic that nonselectively agonizes α1 and α2 adrenergic receptors. The fullerenes family especially C60 derivatives have appealing photo-, electro-chemical and physical properties for biomedical applications including acting as pro- and anti-oxidants.

Parkinson's disease is a degenerative disorder of the central nervous system. It results from the death of dopamine-containing cells in the substantia nigra, a region of the midbrain; the cause of cell-death is unknown. Procyclidine is used to treat parkinsonism (slowed movements, stiffness of the body, uncontrollable body movements, weakness, tiredness, soft voice, and other symptoms caused by damaged nerves in the brain). Procyclidine is also used to treat problems with moving and drooling that may be caused by certain medications for mental illness. Procyclidine is in a class of medications called antispasmodics or antimuscarinics. It works by preventing sudden tightening of the muscles. In this Study at the first compounds [C60- Procyclidine–Cn-2X]+ and [Procyclidine-Cn-2X]+ (X=F,Cl,Br) were optimized (n is similar to in two compound). All calculations is done in 6-31g* basis set in HF method and in gas phase. The results showed that the energy levels of molecular orbital (HOMO & LUMO) in the RF has the lowest value. C62-X, C62-N61 has a length of the shortest bond and the bond has most power. Comparison of the dipole moments of compounds shows this trend: R-2Br > R-2Cl> R-2F.This is noticeable that the trends in these compounds are quite similar but the values in only drug are more intense than drug with fullerene.
