1. Ebikolwa by’okuziyiza obuwuka obuleeta obulwadde bwa AOD9604
Akakwate akaliwo wakati wa oxidative stress n’obulwadde
Oxidative stress kitegeeza embeera nga, wansi w’ebintu eby’obulabe eby’enjawulo, omubiri gufulumya ebika bya oxygen ebisukkiridde (ROS) n’ebika bya nayitrojeni ebikola (RNS), ekivaako okwonooneka kw’okwokya okusukka obusobozi bw’omubiri okugogola ebika bino. Obutakwatagana buno wakati w’enkola za oxidative ne antioxidant kivaamu okwonooneka kw’ebitundu by’omubiri. Endwadde nnyingi, omuli endwadde z’emisuwa n’emisuwa, ssukaali, endwadde z’obusimu, n’endwadde z’ekibumba ezitali za masavu (NAFLD), zikwatagana nnyo n’okunyigirizibwa kw’okwokya. Mu mbeera zino ez’obulwadde, emiwendo gya ROS egy’omu butoffaali egy’okugulu gilumba biomolecules nga lipids, proteins, ne DNA, ekivaako obutoffaali obutakola bulungi n’okufa.
AOD9604 Enkola y’okukola mu antioxidant
AOD9604 ekola ebikolwa byayo nga etereeza enkola ya enzyme antioxidant mu butoffaali. Superoxide dismutase (SOD), glutathione peroxidase (GPx), ne catalase (CAT) zikulu nnyo mu butoffaali obuziyiza obuwuka obuleeta obuwuka obuleeta obuwuka obuyitibwa ROS n’okukuuma bbalansi ya redox mu butoffaali. AOD9604 eyinza okulinnyisa okwolesebwa oba emirimu gy’enziyiza zino eziziyiza obuwuka, bwe kityo n’eyongera ku busobozi bw’obutoffaali obuziyiza obuwuka obuleeta obulwadde. Ku luuyi olulala, AOD9604 eyinza okwetaba butereevu mu kuyoola obuwuka obuyitibwa free radicals. Ebibinja ebimu mu nsengekera yaayo eya molekyu biyinza okuba n’obusobozi okukwata ROS ne RNS, bwe kityo ne kikendeeza ku kwonooneka kwazo eri obutoffaali.
Mu kunoonyereza okwakolebwa nga bakozesa enkola y’ebibe ey’obulwadde bw’ekibumba obw’amasavu obutali bwa mwenge, obujjanjabi ne AOD9604 bwavaamu okukendeera okw’amaanyi mu miwendo gya malondialdehyde (MDA) mu bitundu by’ekibumba. MDA kiva mu lipid peroxidation, era emiwendo gyayo egyakendedde kiraga okukendeera mu oxidative stress. Enkola ya SOD ne GPx mu kibumba yeeyongera, ekiraga nti AOD9604 eyinza okukendeeza ku kwonooneka kw’okunyigirizibwa okw’okwokya (oxidative stress damage) ng’eyongera ku mirimu gy’enziyiza eziziyiza obuwuka obuleeta obulwadde. Kino kiraga nti AOD9604 erina akakwate akalungi ku kulongoosa embeera ya oxidative stress mu kibumba, okuwa obujulizi obw’okugezesa ku kukozesebwa kwayo mu kujjanjaba endwadde ezikwatagana.

Mu nkola y’ebibe ebinene ennyo, okukuba empiso ya AOD9604 mu lubuto okumala ebbanga eddene kyavaako okukendeeza ku buzito bw’omubiri n’amasavu mu mubiri. Ekikolwa kino kiyinza okuba nga kikwatagana n’ekkubo lya β-adrenergic naddala β (3)-adrenergic receptor (β(3)-AR), ekirungo ekisookerwako eky’okusaanyawo amasavu mu adipocytes. Oluvannyuma lw’ennaku 14 ez’okuweebwa AOD9604 mu mbeba ezigejjulukuka, omutindo gw’okwolesebwa kwa β (3)-AR RNA gweyongera, ne guzzaawo emiwendo gya β (3)-AR RNA egyanyigirizibwa mu mbeba ezigejjulukuka ku miwendo egigeraageranyizibwa ku egyo mu mbeba ezigonvu, bwe kityo ne kitumbula lipolysis n’okutumbula lipolytic sensitivity. Mu mbeba β (3)-AR knockout, okukozesa AOD9604 okumala ebbanga eddene kwalemererwa okuvaamu enkyukakyuka mu buzito n’ebikolwa eby’okutumbula amasavu nga mu mbeba ez’ekika ky’omu nsiko ezifuga, ekiraga nti β (3)-AR ekola kinene nnyo mu kulungamya AOD9604 mu kukyusakyusa amasavu. Mu kugezesa okw’amangu, AOD9604 ekyayongera ku nsaasaanya y’amaanyi n’okuziyiza amasavu mu mbeba ezikoona obuzaale bwa β (3)-AR, ekiraga nti AOD9604 era eyinza okukwata ku nkyukakyuka y’amasavu okuyita mu makubo amalala.
Ekifaananyi 2 Enkola ya ddoozi emu eya buli lunaku mu lubuto (ip) eya saline, AOD9604, oba human growth hormone (hGH) ku nkyukakyuka mu buzito bw’omubiri mu mbeba ensajja ezigonvu C57BL/6J (A) oba ezigejjulukuka (ob/ob) (B) mu nnaku 14.
Ebikosa enkyukakyuka y’ebirungo ebizimba omubiri (carbohydrate metabolism).
Mu nsonga z’okukyusakyusa kaboni, AOD9604 eyawukana nnyo ku hGH. Okugezesebwa mu malwaliro kulaga nti AOD9604 terina kye yeekolera ku miwendo gya IGF-1 mu musaayi, ekikakasa endowooza nti tekola kuyita mu IGF-1. Ebivudde mu kukebera okugumira glucose mu kamwa byalaga nti, obutafaananako hGH, AOD9604 tekwata bubi ku nkyukakyuka ya carbohydrate. Kino kitegeeza nti AOD9604 esobola okulungamya enkyukakyuka y’amasavu awatali kutaataaganya nkyukakyuka ya kaboni eya bulijjo, ng’ewa enkizo ey’enjawulo mu kulongoosa embeera y’enkyukakyuka y’emmere.
Ebikosa enkyukakyuka y’ekibumba
Mu kunoonyereza ku mbeba ezirina obulwadde bw’ekibumba obw’amasavu obutali bwa mwenge, AOD9604 tekoma ku kukosa nkyukakyuka ya masavu wabula era etereeza embeera y’enkyukakyuka y’ekibumba okutwalira awamu. Ng’oggyeeko okukendeeza ku situleesi y’okwokya, AOD9604 eyinza okulongoosa hepatic steatosis nga etereeza okwolesebwa kw’obuzaale obukwatagana n’okukola amasavu, entambula, n’okukyusakyusa mu kibumba. Kiyinza okukwata ku kwolesebwa kw’enziyiza enkulu nga fatty acid synthase (FAS) ne acetyl-CoA carboxylase (ACC), okukendeeza ku kukola asidi w’amasavu mu kibumba, okutumbula fatty acid β-oxidation, era bwe kityo ne kikendeeza ku kukuŋŋaanyizibwa kw’amasavu mu kibumba.
3. Ebiyinza okukozesebwa mu AOD9604's Dual Action
Okukozesebwa mu mugejjo n’endwadde ezikwatagana n’enkyukakyuka mu mubiri
