Porphyrin Synthesis Carrier Carboxylic Group as a Ligand for Radiopharmaca Kit: Exploring New Potentials in Cancer Diagnosis

Introduction

Porphyrins and their derivatives have been extensively studied as photosensitizers in photodynamic therapy, a promising method of cancer treatment and diagnosis. The porphyrin structure can be modified both in the Meso position and in the center of the molecule through complexation with metal ions, making it easier to label with radionuclide. This modification not only increases the solubility of porphyrine but also opens opportunities to design ligands in making radiopharmaca kits that are more effective for the diagnosis and therapy of cancer.

Background

Porphyrins have been widely used in various applications, including photodynamic therapy, biosensing, and catalysis. The modification of porphyrin structure through complexation with metal ions has been shown to enhance its solubility and stability. Additionally, the introduction of carboxylic groups into the porphyrin structure has been found to improve its ability to bind with radionuclides, making it a promising ligand for radiopharmaca kits.

The main objective of this study is to synthesize porphyrin carriers with carboxylic groups as ligands for radiopharmaca kits. The specific objectives of this study are:

  • To synthesize porphyrin compounds with meso substituents containing carboxylic groups

  • To evaluate the potential of the synthesized porphyrin compounds as ligands for radiopharmaca kits

Materials and Methods

The synthesis of porphyrin compounds was carried out using 3-hydroxy-4-carboxymethytileochsibenzaldehyde, pyrol, and 4-pyridinkarboxyide in propanoic acid at a temperature of 150-160 ° C for 4 hours under a nitrogen atmosphere.

Results

The synthesis results produced two porphyrin compounds: 5,10,15,20-tetracis (pyridil) porphyrine (H2TPYP) and 5,10-BIS (pyridil) -15.20-BIS [(3-hydroxy-4-carboximethythoxy) phenyl] porphyrine (H2BPYCP).

Characterization of H2TPYP

H2TPYP is in the form of purple powder with a melting point above 300 ° C and a yield of 10.4% (51 mg). The visible light spectrum shows the maximum absorption peak (λmax/nm) at 416, 512, 545, 587, and 642. The infrared spectrum shows the band = NH at 3367.1 cm-1 and C = C at 1457.9 cm-1. The 1H RMI spectrum indicates the chemical proton shift signal at -2.93 (s, 2H, inner n-H), 7.12 (s, 8h, β-H), 8,16-8.17 (D, 8H, pyridine 2 -H and 4-H), 9.07-9.08 (D, 8H, Pyridin 1-H and 5-H).

Characterization of H2BPYCP

H2BPYCP is a brownish green powder with a melting point of 192-195 ° C and a yield of 33.42% (213 mg). The visible light spectrum shows the maximum absorption peak (λmax/nm) at 415, 511, 546, 588, and 644. The infrared spectrum shows the OH group from COOH at 3428.8 cm-1, C = O at 1558.2 cm-1 , and CO at 1415.49 cm-1. The 1H RMI spectrum shows the proton chemical shift signal at -3.09 (s, 2H, inner N-H), 4,62 (s, 4H, CH2 on carboxylic benzen), 7.02-7.03 (D, 2H, benzen carboxylate 1'-H), 7.33 (S, 2H, Benzen Carboxylate 4'-H), 7.45-7.46 (D, 2H, Benzen Carboxylate 2'-H), 7,72-7.73 ( D, 4H, Pyridin 2-H and 4-H), 8.45 (S, 4H, β-H), 8.59-8.61 (D, 4H, Pyridin 1-H and 5-H), 9.69 (S, 4H, β-H).

Discussion

The results of this synthesis open up opportunities for the development of porphyrine as a ligand in the radiopharmaca kit. The carboxylic group in H2BPYCP allows labeling with radionuclide which can improve the ability to diagnose and cancer therapy. Further research is needed to evaluate the potential of these two porphyrine compounds as ligands in the radiopharmaca kit, as well as to optimize the synthesis and characterization process.
