What does HIKMET SIPAHI research?

Dr. Sipahi studies the effectiveness of different treatments for severe infections, addiction recovery, liver protection, and cancer. He investigates how compounds from plants may provide new options for treating inflammatory and cancer-related conditions. For example, he has researched curcumin films for localized oral treatment, special gels for wound healing, and plant extracts that reduce liver damage from common pain relievers. His studies often involve the development of innovative drug delivery systems that improve medication efficacy and safety, such as enhanced ibuprofen formulations and antibiotic combinations.

Key findings

  • In a study on heroin addiction recovery, 74% of patients showed improved psychiatric symptoms after treatment, with a significant decrease in neopterin levels (p=0.021).
  • In treating urinary tract infections caused by carbapenem-resistant Klebsiella pneumoniae, 87.5% of patients treated with fosfomycin experienced clear infections, although 37.4% died within a month due to underlying health issues.
  • Dr. Sipahi developed a mucoadhesive buccal film with curcumin that released the active ingredient steadily over 24 hours and demonstrated anti-inflammatory effects.
  • His work with plant extracts revealed that Sideritis congesta significantly protected liver cells from acetaminophen-induced damage by restoring protective enzymes.
  • Research on new ibuprofen-salt forms indicated they dissolved significantly better than standard ibuprofen, showing 6.11 mg/mL and 7.81 mg/mL solubility for the new salts.

They created 33 compounds and found that one compound, 5e, inhibited cancer cell growth with an effectiveness comparable to the standard treatment drug cisplatin. Additionally, two of the compounds showed strong inhibition of a key enzyme related to brain tumors without harming healthy cells. Who this helps: This research benefits patients with glioblastoma by offering potential new treatment options.

Human & experimental toxicology

Reis R, Orak D, Yilmaz D, Cimen H, Sipahi H

Plain English
This study looked at how two natural substances, eucalyptol and curcumin, can help protect lungs from damage caused by cigarette smoke. The researchers found that these substances improved the survival of lung cells and reduced cell death and inflammation caused by cigarette smoke. Specifically, the combination of eucalyptol and curcumin significantly lowered oxidative damage and inflammatory markers, suggesting they might help treat lung diseases related to smoking. Who this helps: This benefits patients with smoking-related lung diseases, such as COPD and asthma.

Archiv der Pharmazie

Buran K, Reis R, Sipahi H, Önen Bayram FE

Plain English
This study looked at modified versions of a natural compound called coumarin to see if they could help reduce inflammation. Researchers created 38 new coumarin compounds and tested them, finding that two of them, labeled as compounds 20 and 31, were more effective at reducing inflammation than existing drugs. This is important because it could lead to new treatments for inflammatory diseases. Who this helps: Patients with inflammatory conditions.

Infectious diseases now

Sipahi OR, Erdem HA, Kahraman H, Kurşun E, Suntur BM +12 more

Plain English
This study looked at how well two antibiotics, daptomycin and teicoplanin, treat osteomyelitis, which is a bone infection. Out of 72 patients, daptomycin showed a clinical success rate of 84% (32 out of 38 patients), compared to 88% for teicoplanin (30 out of 34 patients), meaning both antibiotics worked similarly well during the initial treatment phases. These results are important because they suggest that daptomycin is a safe option for treating difficult infections, especially as bacteria become resistant to other antibiotics. Who this helps: This benefits patients suffering from osteomyelitis and their doctors by providing alternative treatment options.

Koksal M, Dedeoglu-Erdogan A, Bader M, Gurdal EE, Sippl W +4 more

Plain English
This study focused on creating and testing new compounds that could help reduce inflammation while being gentler on the stomach than traditional anti-inflammatory drugs. The researchers found that three specific compounds (5a, 5g, and 5h) effectively reduced harmful substances in cells, with compound 5h showing strong anti-inflammatory effects similar to a well-known drug called indomethacin. This matters because these new compounds could lead to safer, more effective treatments for conditions involving inflammation. Who this helps: Patients needing relief from inflammation without the stomach risks associated with standard medications.

Comparison of antioxidant and anti-inflammatory activity profiles of various chemically characterized Turkish propolis sub-types: Which propolis type is a promising source for pharmaceutical product development?

2021

Journal of pharmaceutical and biomedical analysis

Guzelmeric E, Yuksel PI, Yaman BK, Sipahi H, Celik C +3 more

Plain English
This study examined 47 samples of propolis, a substance made by bees, from the Black Sea Region of Turkey to understand their chemical makeup and health benefits. The researchers found that the black poplar-type propolis had the strongest antioxidant and anti-inflammatory properties, showing significant activity levels in comparison to other types, especially with key compounds like caffeic acid. This is important because it indicates that black poplar-type propolis could be a valuable source for creating new medicines. Who this helps: Patients looking for natural treatments for inflammation and oxidative stress.

Plain English
This research focused on creating a new eye drop formulation using brinzolamide, a medication that helps lower eye pressure in glaucoma patients. The scientists developed microemulsions with different concentrations of brinzolamide and tested their effectiveness and safety. They found that these new microemulsions could improve how the medicine is released and absorbed, potentially offering better treatment for those with glaucoma. Who this helps: Glaucoma patients looking for more effective eye drop options.

Turkish journal of pharmaceutical sciences

Tuğcu G, Önen Bayram FE, Sipahi H

Plain English
This study looked at a group of chemicals called quinoline derivatives that can potentially block a protein (c-MET) linked to many types of cancer. The researchers found that their new prediction model effectively identified which of these compounds could inhibit c-MET based on their chemical structure, showing it could successfully predict activity in many cases. Importantly, five of the compounds showed a good balance between effectiveness and safety for further testing. Who this helps: This benefits cancer patients by potentially leading to new treatment options.

Plain English
Researchers studied a new type of gel made with a fungus-fighting drug called terbinafine to treat vaginal yeast infections, which are common in many women. They created different gel formulas and found that two specific gels (G-5 and G-8) were effective at fighting the infection without causing irritation or harm to the vaginal tissue. Importantly, these gels showed better performance compared to existing products, and they remained stable for up to three months. Who this helps: This benefits women suffering from vaginal candidiasis and healthcare providers treating them.
